Problem with the colours shown

Hi there,

I have a problem with some of my photo galleries.
When I click on a product in my category page, for example this one: https://petroneparis.fr/produit/chaussettes-sport/?attribute_pa_couleurs=marine-vert&attribute_pa_taille=39-42
the image in the product page shows the burgundy sample, which is the generic colour for the product.
It is not happening on each of my products and this wasn’t the case before so I guess it’s since the last update of the plugin. I didn’t change anything on my back office.

Has anybody seen the same problem? Any idea how to fix this?

Many thanks,
Marion.
