Variation swatches does not stay selected and there are two swatches sets

Hello!

https://orangealmostnaked.com/product-category/spring-summer-2021/

I have two problems on each shop pages:

1 – When I click on a colour swatch (the ones that makes the variation photo of the product change, it is the first row of swatches) it doesn’t stay selected. I want to to stay selected when I click on one of the swatches.

2 – There is still two set of swatches. One that changes the photo of each colour variation, that is the one I want, and another set of swatches that doesn’t change the photo of the variations (I want to remove those swatches).

How can I stay only with the set of colour swatches that changes the photo of the colour variations, but also make it selectable?

Thank you!

(if it can help, I am also using a plugin named Display product variations dropdown on shop page)
