What happened?

Following the "How to Use: Users" guide to add more slots into my personal modpack, I can do the example "egg" slot, but any modded items don't work using the same steps. The slot gets added to the list, but mod items never get registered after being listed in their respective jsons. For instance, just one example, a "Battery" slot was added in the .toml and a "Battery.json" was created which added the registry name of the IntegratedDynamics battery:

I've attempted many mod items. A "datapack" slot for AE2 Crafting Terminal, a "battery" with several RF cells from various mods, and a "chalice" slot for evilcraft's chalice.

How do you trigger this bug?

1. Attempt to add any mod's items to curios slots

You need to lowercase your tag file name (i.e. "Battery.json" -> "battery.json").

That worked perfect, thank you!
Should the wiki page be updated to include that it needs to be lowercase?

Sure, updated it just now to make it clearer.
