I have Blueprint, Biomes O Plenty, and Farmer's Delight on my Curseforge 1.16.5 modpack, and the Farmer's delight integrations, being the cabinet types, seem to be missing.

Please search for pantries instead of cabinets in the 1.16 version and get back to me on that!

Yep, that was the problem, I would recommend you change the terminology on the curseforge to pantries instead of cabinets.

The 1.16.5 version is no longer officially supported, so it wouldn't make much sense to change the terminology to the older name. But since this was resolved I am going to close it now!
