All Items in Incendium are Either Reskins, or not in my Game?

[rare nacelle]

Using a 1.20.1 forge server on version 47.2.0, wondering why this could be and if there are any solutions? All the other mods I have are listed below

[runic veldt]

Are you using the [[Sparkles]] resource pack

[rare nacelle]

I just did, are you supposed to not be able to look up any items under JEI (Just Enough Items)? I also have the datapack installed.

[sonic niche]

this is because incendium is a datapack / a datapack packaged as a mod

Everything is based off vanilla items

ah okay, thank you
