Here's a weird one. I have been running facial recognition on a very large collection of photos, and it is going fine. But now suddenly, in thumbnail view, when I click on the name below a thumbnail to edit it, it turns to white-on-white text, and I can't see what I am typing, nor can I see any suggestions from LR from the list of already-entered names, as I could before.
I am working on a small screen (a Surface Pro), with a large number of people, so dragging the photo to a face is not an option. If I double-click and open the photo, I can edit the name as usual, but this takes more time, and I have thousands to do.
I have no idea what setting might have changed. I am using dark mode. Thank you for helping out a newbie!
