Issue

I have a template (For a Host) that pulls in related content (For that Host’s Events). The second template pulls in related items to that Event (Hosts & Shows). When the Event template is used in a Events collection loop, the Hosts & Shows related content populates properly. When called inside the Host template, those related fields do not populate.

Templates:

This is the Event Card Template

In it you’ll see there‘s 2 related templates for pulling in Hosts & Shows related to this event. This works when just displaying the Event template in a loop, but when this template is called inside another template, the related templates don‘t get populated.
