Minecraft Windows 10 Bedrock Edition Skin changing not working

Whenever I try to switch my skin by importing a custom one, it doesn't work! Sometimes it even appears on the alex model while I want it on the steve. Then other times it doesn't show up at all! Not only is this the problem, but when I'm playing multiplayer with my friends, my skins show up on their skin and their skins show up on me. It's a very messy situation and it's been a problem for over a month now. Can we please have a fix soon? I've finished up a role play minecraft story I created for me and my friends which requires me to change skins a lot :c
