Whenever i try to do it with an iron shulker boxes shulker box in my inventory it says this in the server console and does not do anything,

When removing shulker boxes from my inventory, it gives this error instead, only places one block without consumption, and kind of does some fuckyness with iron shulker boxes?

looks like it happens if youve just had iron shulker boxes shulker boxes in your inventory at any point on the server

it works normally on singleplayer though?
