I had already created the swatches and variations for the products using a Yith plug in. Now I installed WP clever bought together plug in but the variations menu is ugly with text only, I wanted to use the swatches. 

I installed the WPclever swathes plug ins but I can't get it to work with the bundle. How can I get it to work? Should I delete Yith plug in and start from the scratch creating the swaches in wpclever plugin?

(see the image attached, above the good variant selector and below the wp clever bundle ugly selector).

thank you
