WowAce

Returning after not playing for 2+ years, but I log on a minimum of 1x monthly to update my addons. My bars are still in the locations I placed them but the spells/actions they were populated with are gone. And it looks like some were re-named as "Class Bar". I'm hoping to get guidance - I have many toons, I want to start playing again but I need to figure this out first. Hopefully I won't have to redo all of my bars on all of my toons. If it helps, I tried re-selecting profiles (Disc Priest, then Holy Priest) - it didn't help.
