Nest buttons on prototype?

So I have this prototype where I’m supposed to click on a radio button to change it from unselected to selected, I made the animation but if I click on a button to select it, the second one is shown as also selected on another frame. I guess that violet square is showing me where I’m using the exact same button but it’s the first time I’ve seen this.

Can someone tell me why it’s this happening? The right thing would be to select one button on the first frame, and to select another button on the second frame and so one, they shouldn’t be already selected on every frame 😦
