Button animations not being called right away

I made a bunch of animations for three buttons. The first one works correctly. When ever I mouse over it, the size increases. But the other buttons don’t play their animation when I mouse over it. I have to wait a couple of seconds, and then the animation plays.

Have you tried checking the animations are set up correctly in the animation tab? alt text
Make sure the animation starts at 0, with no delay

All the animations have no exit time or transition duration, except for the normal state
