You didn’t describe the source of the pasted block. I’ll assume it comes from another Writer document.
When you copy a block in Writer, everything is transfered to the clipboard: text and metadata associated with it, i.e. styles and other formatting.
Everything again is pasted by default (unless you
Paste Special to choose which data will be pasted). This means you also paste the metadata.
When you select a paragraph style from the toolbar menu, you effectively assign this style to the paragraph or selected block. But you must be aware that this changes only the paragraph layer. Styles in Writer are organised in layers:
- paragraph style
- character style
- direct formatting
Set (or “forced”) character style attributes override the corresponding ones in paragraph style. Direct formatting attributes override both those in character and paragraph layers.
If the copied source block has direct formatting in it (e.g. you used
B to embolden some characters or the toolbar menu to change font size), this direct formatting is kept in its overriding layer, preventing the paragraph style attributes to surface.
You can tell this is what happened by selecting the pasted block and
Clear Direct Formatting to erase the DF layer.
If you want to try a “professional” approach to document formatting, never direct format. Use styles instead. You can do much better and more versatile with them than direct formatting. Read the Writer Guide for an introduction to styling.
