Templates are not generating correctly. Items are missing.

[CapitalF]

I have a problem where items are not showing up in my shop correctly. The item is in Acquisition plus, I have priced the item, and I've looked at the template preview, but the item isn't there. I can tell by setting a unique price and looking for it in the preview template.

I suspect that other items are also missing from my listings, which is why I started investigating in the first place.
