Dropdown arrow showing on other swatches types

Hello,

Is there a way to avoid the dropdown arrow shows over Lable/Button and Color Swatches? It makes almost unreadable the product sizes’ labels. I tried adding custom css, but I don’t find a way to get rid of them. I don’t see that problem in your demo, so I don’t know if it could be a conflict with my theme or something else.

I’m sharing a link to a product that shows my issue.

Thanks beforehand for your help!
