Product Page: Image gallery does not hide images in variable products when you change from one color to another

Hello,
I bought the theme and everything works very well with the exception of the photos on the product page, for example when you make a click on a configurable product of various color the photos of different colors remain active in front end and are not hidden even when you are in another color and are other photos.
We are using the latest version of the theme, Magento 2.4

I see this same error replicated on your demo page: https://pearl.weltpixel.com/v7/grayson-crewneck-sweatshirt.html

Any idea if it is a bug in Magento 2.4 or is it the extension of the gallery that brings the theme?
