A preliminary remark: your document is in the ~300 pages range. With such a size, it is impossible to control formatting unless you adhere to a very strict method. Unfortunately, you have a can of worms mixing (bad) styling with (heavy) direct formatting. Additionally; spaces and empty paragraphs are used to space “elements”. This is very detrimental to the stability of your layout (space width is adjusted by Writer independent from you; empty paragraphs may be flushed to other pages because of edits and will kill your layout or cause spurious blank pages). Many paragraphs are Default Paragraph Style (with direct formatting) though this paragraph style, intended to set attributes forwarded to all other styles, should not be used for text, due to its technical role of “ultimate ancestor”.
Style name should denote the significance of the paragraph, word, page, … to which it is applied, not a description of its visual effect.
Many equally significant paragraphs are styled differently, e.g. Body Text and No Spacing (this name is an example for the preceding remark, and I don’t see differences with Body Text except a little inconsistency in Spacing below). No Spacing is also applied to descriptions of keywords whereas you should have created a Description paragraph style with adequate configuration instead of indenting with direct formatting. You created No Spacing outside any style hierarchy, preventing this style from benefiting attribute inheritance.
Some paragraphs are Preformatted Text while this style is in tended for fixed-pitch text (mono-spaced fonts) where spaces are used to layout text. Your paragraph are just “ordinary” text with variable pitch.
You don’t use consistently character styles, apparently preferring direct formatting.
I could add list many other design errors in your style and writing routines but this is not the subject of your question. Nevertheless, I encourage you to stop writing for a while and deeply think about your styling in order to facilitate formatting optimisation and layout tuning.
Numbering size
You rightfully configured your heading numbering with Tools>Heading Numbering. But you forced Character style: to Numbering Symbols, meaning you intended to give the numbers a distinctive look different from the heading.
You have “touched” Numbering Symbols Font tab. You set font size to 11 pt. Or perhaps you set the font size to some other value and later realised it did not give the expected results. You decided to reset the style to its initial state. Since in the initial state it listed 11pt, you selected 11pt. You then stumbled on an undocumented behaviour of style configuration, due to a limitation in style display.
You must first remember the style precedence rule. Character styles take precedence over paragraph styles. If the same attribute is set in a paragraph style and in a character style, the value in the character style is used. And in case you also have direct formatting, direct formatting takes precedence over character and paragraph style.
The undocumented behaviour is: whatever you “touch” in a style configuration is set action. Binary attributes, represented as a check box, have 3 states: “transparent”, set and unset. Multi-valued attributes, represented by a drop-down menu with n choices, have n+1 states: “transparent” and the n choices.
“Transparent” means the attribute is not set in this configuration and its value will be inherited from its ancestors. Any set action blocks this inheritance, forcing the value to what you have set. Unfortunately the UI can’t show “transparent” state. It display inherited value the same as a set value.
In your case, there are two solutions:
- reconfigure
Tools>Heading Numbering to set Paragraph style: to <None>, reserving Numbering Symbols to other usages, e.g. list number
- reset Numbering Symbols to its initial “transparent” state
For that go to the Font tab and press Reset to Parent which will wipe out all manual settings in the page. Then you can re-establish your “mandatory” settings without touching font size.
Numbering Symbols has no ancestors. Consequently the reset action puts it into full transparent state.
Final advice
Review thoroughly your styling to get rid of direct formatting and organise methodically and systemically (meaning, use a consistent semantic naming scheme) your styles.
