I updated to build number 1726 today, and after doing so, all of my themes are named “Name”. They’ve also reverted to the default colour palette, and I can’t create new ones. I’ve tried logging out and back in, as well as completely reinstalling, but the issue persists. Also, I’m pretty sure the checkmark next to all of them isn’t intended behaviour. I have no idea how to reproduce the bug, as all I did was log out, update, and then log back in. Logs can be found below.
