Selecting different button once button already selected doesnt work unless button is toggled back to deselected state.

Hello,
We were trying to implement your plugin on an ecommerce site we are building.
However, we are noticing if we click a button, it selects.

However, if we then click one of its siblings it doesn't select immediately. You either have to click the button three times to get it to take effect, or if you select a button, then click it again to deselect it, THEN you can make another selection that works.

You can see this on this page (the color variations).

Any ideas what is happening?
