AFAIR it's a known bug that flags remain when I open another database. So when the title exists there, too, it will get flagged. When I switch back to the original DB the titles are still flagged.

But now I discovered something else. I switched the databasse, forgot that I had flagged profiles, flagged a few more and exported them to XML. Suddenly I had a whole lot of "empty" profiles in my XML (no ID, no nothing).

It's still in 3.7.2.144
