Hi Mor,
Thanks for reaching out to us. Can you please contact the JET support team and ask for an action hook to push the swatches on their slider product loop?
Basically, some plugin/theme changes the default hooks of WooCommerce. In that case, swatches will not display where there are no basic hooks of WooCommerce.
Thank You
colors of the product would not be added to my sliders

I thought that the colors of the product would be added to my sliders (I use JET) but it is not added.
