Image Swatch should work independently

Hi,

I have noticed that when ever there is 2 variation fields to choose from, for example, colour/style(Variation Image Swatch style ) and other like size or something in button dropdown format.

User has to choose size 1st then only variation images will change.

but if you looks from customer perspective, they 1st see the different design by click variation images and further select the size. We also feel little bit drop in our average order numbers post this thing.
As not all customers are internet geek, 3 customer asked us same thing over our live chat, like why design not changing/ how to see other designs, like that.

hope you understand. will share the screenshot in another mesg
