Is Dismantle off the GCD by any chance? That's the only thing I can think linking the two together.

Dialog buttons being reversed can be fixed, for some reason I never noticed it. Defaults being off can also be adjusted.

Edit: It's not a bug (well, it kind of is), you've got the Usable checkbox ticked I presume? That check will fail if you're lacking the energy to use Kick/Dismantle. As you've also presumably got it inverted, it's showing because it says "I'm not active", and the invert toggle then says "Oh yes you are!".
