CustomPress CPT not showing up in search results by Category

Hi everyone,

I made a custom post type using CustomPress. I allowed it to have tags and categories, and included TRUE regarding querying and showing up in search results. It's also set to public and I think that everything is correctly set.

When I try to create a file called category-slug.php, and I do a query, regular posts are showing up but not the CPT's. I have searched for hours but to no avail.

Can anyone help me out here? I'm kind of lost.

Thanks !!
