Can't control Phat constraints rotation anymore

I’ve imported new character and tried to create Phat for it. But when I’ve started to setting up constraints I’ve found out that I can’t control Angular Limits anymore. It’s no matter how I rotate constraint it’s always behave like it’s turned down, any axis
About month ago I’ve created phat in 4.20 and it was ok, now (in 4.21) I tried to edit that and it’s not working too!
Is it known issue? What should I do?

Ok, I tried create Phat in 4.20 in new project with same character and it’s work like it should. Seems like it’s 4.21 problem. How can I send bug report?
