CP category not working

Having some issue with CustomPress custom taxonomy slug not display under WordPress category.

Basically, I've changed the default 'category' slug under Settings > Permalinks to "thema", created a custom post(gruppenspiele) along with a custom taxonomy(ort) associated with it.

The posts under custom taxonomy and custom post type slug displays(https://domain.com/ort/indoor, https://domain.com/gruppenspiele/peng). But not the custom post-type category(https://domain.com/thema/kreisspiele).
