Well, the custom content region was not showing. When I added in another simple region of the same name <?php perch_content('Languages');?> it did load, but loaded twice. So I removed that new one and now it's fine?

Originally but before use in CMS changed to custom content region to send variable into template - doesn't that do the same thing... ?

So on this page: https://docs.grabaperch.com/docs/templates/passing-variables-into-templates/ the "...and merged with the regular content." means you need to a standard content tag to load custom content??

As I have said, when we added the normal create content tag it loaded, but loaded twice, so we then removed the content tag again, it then worked, obviously because it's in database now - but I thought the custom content would have done this?

Then why when I have the "perch_content_custom" and "perch_content" the content template loads twice?

"Both will output the content of the region.."

Then why when I only have custom_content does it not load?

"...then pair it with perch_content_create() to set the region up."

What does this mean? Do you need standard content region to trigger custom content to load?
