Can't rename panels in 4.1

I can’t seem to rename panels in 4.1.

I have tried unlocking the scene and panel names repeatedly, to no avail. For some reason, in a few scs. board pro has numbered my panels 1, 1A, 1B, 1C etc. I really just want them to be 1, 2 , 3, 4 etc. but cannot change them.
Anyone encountered this and have a fix?

Sounds unusual. Have you tried contacting Support to have a look on your system?
