Bookmarks move around to consistent locations (just not where I want them)

Hopefully not too confusing of a title. Whenever I create a new bookmark, or move a bookmark around, there comes some point where the bookmarks are moved. Not back to their previous location, not alphabetically or anything, just moved. The positions they move to appear to be consistent, but not to the locations I want them to be. This happens no matter what device I'm using firefox on, whether or not I have sync enabled. I've tried some of the solutions some mention, but the main difference with my problem is that new bookmarks stay (meaning my profile isn't broken and sync is working). Any help would be appreciated.
