Glitched Wood Box?

Trying to figure out what I’m doing wrong. I just got back into RS after not playing for a couple of years and discovered woodboxes and ore boxes in the game.

Clicking fill on my orebox fills it with all the spirits in my inventory and everything seems to work as intended, but when i do the same on the woodbox, it doesnt place spirits in it. I also tried manually clicking the spirits and then the box.

The woodbox is a teak wood box (i upgraded it thinking that would help) and the spirits i am trying to put in it are from minotaurs (oak and regular).

Am i missing something? Is there an NPC i need to talk to? Am I just dumb or is the game glitched?
