Reply To: Color OR Size selection in shop page

https://woodmart.xtemos.com/shop/demo/electronics/?demo=electronics

On this website, i can select variation by clicking on the color below of the image ( like for the wood smatch or the clock item, then that variation is directly added to the cart ( thats how i want it )

On my shop however, i can click on variation, the color changes, but still when i click Cart item, i have to select variation again ( despite it has already been chosen )

Hope im clear, thanks
