How can I save my Page Styles more permanently?

I use LibreOffice to format paperback books, and I need to use multiple styles (for the sake of page numbers, for example). However, I notice that some elements of my Page Styles reset when I close and reopen the document. For Organizer, if I say Convert 1 will follow Convert 2 (rather than the default Convert 2 will follow Convert 2), this will be gone by the time I reopen my document. I wish there was a way to save my formats, because often it means a lot of reformatting on my part.

Don’t post as Wiki, it helps no one.

By chance, do you save your docs as .doc(x)? M$ formats have no notion of page style, which could explain what you experience.
