I'm excited to be exploring version 15, but it began with a thud, not a bang: a strange typeface has crept into my database. In various places of an otherwise steady and long-maintained file, a symbol-like face named Z@R8BB9.tmp has infiltrated numerous elements. If it were simply that I had to edit my layouts a bit, I would chalk it up to an annoyance. But as you can see in the attached screen image, portal labels and tabs have also been assigned to this face, and I have no idea how to change those.
Any idea what is going on here? I don't mind doing a reinstall, if that is the best course of action here.
