Default Style won't stay default

Okay… this happened… sometime last night I think.
Anyway, I was writing a document… and all of a sudden, the Default Style (Literally it’s the default style title and all) changed to ‘Text Body’ when I made a new paragraph and I hate it.
So… if anyone could PLEASE help me so I don’t have to keep manually changing it back, it would be great.
Oh, and it’s the recent LibreOffice 6.04 I’m using… in case that had something to do with it.

Well, it isn’t emphasised enough: Default Style has never been intended to be used for text entry. It is some sort of “reserved” style allowing user to set his personal preferences (not those of developers or any stranger). Default Style properties propagate to all other styles. As such, its properties have a “universal” value, common to text, headings, headers, notes, etc.

The “normal” style for text is Text Body which is a direct descendant of Default Style.

The problem arises from the way a new blank document is initialised. A brand-new empty document contains nothing and all its properties are “void”. The consequence is the initial empty paragraph has no style which displays as Default Style.

If you start typing, subsequent paragraphs inherit style of the preceding one. But if you insert some kind of heading styled with Heading n, when you hit Return, next paragraph is styled with the one designated in the Next Style property of style definition, Text Body in this case. Now, you are in the implicitly intended style for text entry.

My advice: unless your document is not structured (no Style n headings, no style at all), use Body Text for common paragraphs. Leave Default Style for globally changing your document formatting from a single location.
