Smart Animate not working -- just dissolving

I’m trying to make this button have a circle enlarge over it to transition to the white button in the middle, then on click have it go to that grey button on the button – and then back to default when the mouse leaves the last button (which means the circle should shrink back to original.

Whenver I play the frame, it dissolves instead of smart animate. What am I doin’ wrong? https://www.figma.com/design/nJNnAU8I1Veerzhbul9uvh/Untitled?node-id=0-1&t=tvGf7sQM8Ly7qfre-1
