Prestashop 1.7 product page not adding atributes to cart

[Juan Rios1]

In this picture, I added this product to my shopping cart with the color "Crazy tan" and size 28. But it's not saving the size in the shopping cart.

http://test.riograndeboots.com.mx/bota-de-trabajo/424-6488-bota-de-trabajo-200-rgw-suela-rgw-durabilidad-extrema.html#/194,color,crazy-tan/363,talla-calzado-hombre,265

this is the url to this product, but it happens in all of them except for clothes.

I'm using the latest prestashop version.

I have turned on debug mode but get no errors, hopefully someone has had the same problem and can help me.

Thanks
