Variation swatches problem in product preview

Hi!

Products with variations are shown with an extra frame around it. It seems as if the colors that are options to choose from are hiding behind ‘select options’ (‘opties selecteren’ on my site), next to ‘quick view’ (‘snel bekijken’ on my site).

This is the case since the recent updates from woocommerce and wordpress, before that it was shown perfectly: the colors were shown on the product page, not in the smaller product preview in the shop area.

Theme used: Salient.

On the page linked in the site information below, there are a few products. Testproduct is a product without variations and is shown the way I’d like to see again on the products with variations.

Thanks a lot for your time reading this! I hope you can help me out.
