I imported a 50000 items documents .bib (by error of file). So I tried to delete it. As they are imported the same day I deleted it then empty trash. Unfortunately, these 50000 docs reappear constantly, freezing the client. They stay on the server. After several attempts I succeeded to have a local clean library. So I attempted to force sync from local to server but the 50000 docs stays and always come back. I save the correct library in bib and also as a sqlite archive and reopen a new empty account. Now I'd like reimport the correct library in the new account and clean the old one.
