Ever since I moved from Optifine to Rubidium this happens

This is not an issue. Labels don't alter chests in any way

huh, then what how do i hide the chest pins like this?

apparently its not bcus of Rubidium, and even Optifine the chest pins still blocking the label
btw im using
Forge: 43.2.21
Minecraft: 1.19.2

Those chest are simply rotated. If you put the iron bit Infront of course it will show

oh. crap, aight imma close this issue
