Skin Details in Skins included in the Super Mario bundle not showing though armor

When equipping chestplate and leggings, skin details (like tails and shells) disappear.

What I expected to happen:
Skin Details to go though armor like the animal skins.

What actually happened:
Skin details disappear when equipping chestplate and leggings.

Effected skins (Super Mario Skin Pack):

Yoshi
Bowser

(I would take screenshots or a short video of this happening but I do not have any sort of capture device.)
