Google Chrome bookmarks keep showing up after I re-organize them!

Hello! My Google Chrome bookmarks keep showing up after I re-organize them into their appropriate folders on my bookmarks bar.. It's very frustrating because I put a lot of time and effort into keeping everything on my Mac super-organized, just for me to organize everything into folders using the "Bookmark Manager", and then re-open Chrome, to find out that:

-all of my bookmarks are in the "appropriate folders" that i put them in

-all of the bookmarks that were "floaters" (not in a folder previously, just on the bookmarks bar, but were moved into a folder) are returning back to their original positions on the bookmarks bar.. but they are still inside the "folder" as well.. basically creating many duplicate "Favorites" if I then move those into the folders.. and then it repeats over and over

Can anybody help shed some insight on what could be going on here? Thanks!
