Same host skin multiplayer issue/bug

My skin is unique in its kind of way but then players in my or their multiplayer world copies the skin of the host and it is really bugging me off and annoying me. How I got this bug is you go to friend tab and click on the world that you want to join in by your friend and go to the host of the multiplayer server and you will be in the skin of the host. My friends are really annoyed by this bug or issue. Would you mind fix the skin issue/bug as I can use my unique skin again. Thanks!
