Inconsistent styles between formats

[lgsl]

I noticed that the way styles are handled depending on the format is inconsistent. When a file is created in TextMaker and saved as ODT, several of the default styles, like normal, body text and footnote text are handled as custom/user created styles, not as the document-default ones. So if this file is then edited in LibreOffice, styling inconsistencies show intermediately, most notably with footnotes.

Steps to reproduce:

1. Create a document in TM. Add text and apply any default style provided by TM. Do not create custom styles. Add footnotes so you can spot quickly the problem.
2. Save as ODT.
3. Open in LibreOffice and add another footnote to see the difference on styling.
4. On the styling sidebar provided LibreOffice, select the custom filter. There you will find every single style that was applied by TextMaker.

This situation makes it incredibly annoying when exchanging files with other people that use LibreOffice, since the default formats never match, due to TextMaker inability to properly translate default styles to odt's default naming conversions.

I am certain this issue affects to any kind of element that is inserted into the document and that depend of default styles.

Take a look at the attached demo file.

When the file is reopen in TextMaker, TM treats LibreOffice styles as custom and modified them to match its own (the original ones), basically creating duplicates leaving a big mess since how some footnotes have "footnote text" applied, while the others have "footnote" and some paragraphs have "normal" while other "standard" or "body text".
