A user reported that the "cred-delete-relationship" shortcode is not working inside one of the views.
Solution:
Guided that, in the "cred-delete-relationship" shortcode, the "role_items" attribute works in a view where a relationship filter is being used.
Since the view in question is not using any relationship filter, you'll need to replace the "role_items" attribute with the "related_item_one" and "related_item_two" attributes.
