The server I play on is Origin Realms and they use dyed armor as their custom items but they always show up as iron armor on the bar. Saw someone else have their armor bar show up properly according to the armor so that's why i'm confused

can u give me server url?

play.originrealms.com Here it is!

I just played on the server, and my guess is that's not a normal leather armor.
My guess is that the leather armor may have included another NBT tag (for special texture packs), or it may not be the leather armor at all.
More detailed debugging is needed, but there's nothing I can do right now.

Ahh, okay! Thank you for looking into it!
