Bookmarks Sync keeps reverting to old Chrome version

Hello,

I have repeatedly updated my bookmarks on Brave and deleted all the old ones. It stays for about a week but then it reverts and loads dozens of defunct Bookmarks/Folders again which seem to come from a very old Chrome version because my current Chrome Bookmarks tab was, before switching to Chrome, the way I want it ie streamlined.

Please see image, below, also showing overflow arrow which leads to many more old and unwanted folders;

Brave V.1.13.86

How can I ensure I keep the Bookmarks the way I want them after getting it setup?

Kind regards,

I have the same problem and have not found a solution. Leaving Brave soon as this is a lot of work it is throwing away (several times now).
