Many items left in "No folder"

I’m new to BitWarden, but I have been using 1Password for many years now.

I imported data from 1Password, no issues. Everything went into “no folder”, so I moved all my items into “Personal” and “Pro” folders, all in the WebUI. Next, I installed desktop version, inserted my credentials…And all my data was fetched, excepted that everything I moved out of “no folder” is still there, in duplicate.

The thing is: I can’t select all of these duplicates using desktop app, as the app doesn’t allow multiple selection. And I can’t delete them from the webui, as they don’t appear there!

I tried wiping BitWarden desktop app away using brew zap, then reinstalled the app: the duplicates are still there :frowning:

Can someone help?
