Removing a class level breaks class features

[gamesaint]

I added too many levels to my unchained monk, and had to remove one. However, the system immediately began throwing up errors as though I had no class levels anymore. My feats tell me I need “Monk level 1”, so it doesn’t seem to know I have a class at all.

Is there a way to force it to revalidate? I don’t want to suppress all error messages, but I also don’t want to rebuild my entire character. Anyone else seen this issue?
