Swatches are not displayed on category pages

Hey,

I just bought the premium version of your plugin in order to display variations on my category pages (product list). I enabled the “Show variation swatches on the product list” option and also played with the align and position settings. I can’t get the swatches to display on the category page.

To test, navigate the website to a category page using the main menu:
Echipamente > Incaltminte de protectie > Pantofi de protectie and the last products inside that category should display multiple color variation swatches.

Do you how I should proceed in troubleshooting this? thank you!
