Bug - Omen Packages don't change weapons

I’ve tried on different characters but in the skin preview, specifically “Omen Package” and “Omen Special Package,” do not change the weapon skin along with the Body skin.

Basically when you preview the skin, and click the arrows in the preview window to cycle through the colors, the weapons don’t change; they only show the base Green “Dark Omen” skin set no matter what color you choose.
