Variable Product Radio Buttons problem

Hello!
First of all thank you for the excellent functionality and for separating it from the rest of Booster for those who only need this bit.
I’m developing a crowdfunding page for a client, and they want all the rewards visible, so I chose to display Radio Buttons in the settings. This displays just fine, but does not change the content in the .woocommerce-variation div (description, price and availability). No matter what I choose, the page keeps displaying info, price and availability for the first option.
If I use the default dropdown behaviour, information changes according to the selection.
Please help.
