I have tried to check my database, delect all add-ons and even import my file again.
How to solve this problem? I appreciate any help that can offer.

The following in the debug console should fix it.

mw.col.conf["savedFilters"] = {}

Did you import any .apkg files created with a separate tool, or use any add-ons?

Yes. I tried a new tool to import cards 2 days ago. This problem has solved. Thanks.

No problem. Please let the tool author know, so this does not affect other users too.

Hey, I got the same issue but I cannot solve is using the debug console. I use add-ons but the problem stays even if I disable them. Thanks in advance
