Yalms texture messed up while wearing battlesuit

I noticed something very strange when I was fooling around with some old armor.

I had a yalm equipped, and went into a store. While I was in the store, I equipped a battle suit. I left the store, and when I got outside I noticed my Yalm wasn't nice and shiny, but instead had the texture of the battlesuit I had on.

I noticed I could not equip my Yalm while wearing a battlesuit. But it let me keep my yalm equipped when I put on the battlesuit.

Unfortunately, nobody else can see the custom Yalm paint job but me. :( Would have been cool if others saw it like this.
