Exclusions not loading product attributes (only on english product version)

Hi there,
when I try to exclude specific product attributes in the italian version of the product it works but in the english version it only loads the general product and not the attributes.

For example:
If the customer chooses the ‘3cm height belt’ when he goes to the next step he has to see only the ‘3cm height buckle’ prodcut and not all of them (2 cm and 4 cm).

To show this in the wizard I go to the ‘3cm buckle’ product and I try to exclude this product from the ‘4cm height belt’. But the only product that shows up is ‘belts’ and not ‘4cm belts’.

In the italian version it works but in the english version I can not filter products according to their attributions, it looks like the attributions don’t exist.

Hope I explaned it properly.
Thank you
Federica
