Thanks!

What language are you playing in?

American English

Alright. Something must be up with the Lang file then. What version of the mod are you on?

Tokenables 2.0.1 and SkyLib 1.5.1

I think I've found the issue, in the lang file you refer to it as container.iron_chest, but in game it's container.ironchest

All chests are affected, I think the other items are fine.

Yep, just checked and confirmed it. Chests, barrels and shulkers are missing the underscore in their names, while open.
