Hello,

I have test your site and also seen your video. You are using “XT WooCommerce Variation Swatches Pro” plugin, right.

As its a third party plugin and we did not test this in our theme yet. It seems that it is not compatible with our theme.

I suggest you to use the theme default swatches functionality except of using third party plugins.

Follow the documentation for adding swatches by using theme built-in functionality:

Best Regards.
