Get Video from Collection Not available in Webflow editor

I’m trying to add videos from a collection (Cases) to collection items in a section (Blog).

I’ve done this before, but I’m now working with a template, and for some reason, the “Get video from collection” option does not show up in the editor.
The question is: what am I doing wrong. Just adding videos one at a time to each card is not an option for me, so hooking it up to the collection is necessary.

Thank you for any help you can give me.
