This is one of the many parts of the game which doesn't work properly with a UI scale adjustment. You need to temporarily set your UI scale to 1.0 in "interface" before using appearance change or making new characters. This has been broken for a very long time, and no-one seems to be bothered to fix it.
It also affects:
Boons
Chat word wrap
Requesters (e.g. the claims agent, or vendor buy back)
Dungeon scoreboards
..and much more
