Bookmarked pages no longer saving to previously used folder

Hi there, Whenever I bookmark a page on the android app these days, it always saves it to a specific folder. It used to save it to whichever folder I last bookmarked a page to, but it doesn't do that anymore; it's like it's got stuck and by default now, only saves to a folder that I rarely want to save to. That means that every time I bookmark a page, I have to edit the bookmark and save it to the folder I actually want to save it to. As a result of this, I now have to edit at least 90% of my bookmarked pages so that they end up in my preferred folder. Is there a fix please? Many thanks.
