Excellent items visibility

Hi.

I've got a little bit problem, and idk is it a bug, or just a stupid update. :$:
So: Our Team build a Season 9 battlecore MuOnline server, and the excellent items looks like regular items, on the player. It isn't change the color, just like a simple regular item.

My question: Is that a bug, or it's just an unnecessary development?

Thanks the answer! :junglejane:
