Plugin not Hiding Product Categories

Hi, first of all, I love the concept of the plugin, it’s exactly what I need!

However, when I try to hide product categories on the shop page of a demo website that I’m devoloping, nothing is filtered, all categories are showing, even though I’ve assigned the three categores to three user roles. Can you give me some suggestion on why this might be please?

I can send you the login details by email if you need them for testing.
