Choosing color swatch doesn’t show variation image

I have the Pro version of the plugin.

When I’m on the product page and choose a color from the color swatch I assumed it should change the product image that is shown on page to the image I set for this particular variation.

This is what it does on the product list or homepage so I thought it would also do it on the product page.

Is this function not included or did I miss a setting?

Cheers,
Stan
