Bug with skins and problem with connecting to friends

1. Special skins like the jawa, yoda and ewok from the starwars pack and others have a visual glitch in first person showing a exagerated arm when mining, in 3rd person armor is clumped together and friends see me as steve while I have these skins on

2. For some reason I can connect to my friends worlds but they cannot join mine, I'm sure this has nothing to do on your end but I still want to mention just in case it is. Thank you for your time and have a good day and easy shift.
