Hi @harbeckster, welcome to the fourm!

That’s definitely not a normal experience, though it looks like one other user has reported the issue - did you get a chance to read through this thread?

Most of them are working fine, but one gives the error “database disk image is malformed”, and that persists even after a database repair or recreate. What can I do to diagnose further? I was able to open the database with a SQLite tool and it doesn’t seem to be obviously corrupt.
