Feeds not visible in folders


I have created a number of folders containing various links. One day I have noticed that the folders are empty. When I try to open the folder, the only action I see is the "fetching records" in the left lower corner and the folder shows nothing. Howerver, the feeds (from the folders) are still working since I can see their records in the "Unread news" smart feed.

The feeds which are not in the folders are shown fine.

The bug happend some time ago when I was using 3.11 version. I upgraded to 3.12 which did not solve the bug. I run feedreaderbackup and fixdatabase and still no change. Eventually, I could manually copy and create all the feeds again but there are so many of them that in my lazyness I am trying to fix this problem some other way :)

Thanks in advance for any help.

Best regards,

Not all of the feeds but i

Not all of the feeds but i can't see some of them too. Feedreader updates those feeds, i can see them in unread section but i can't see them in folders. So i can't delete them... Weird...
