Skins changing when out of render distance

When my friends and I go on our realm, we have our custom skins.

Whether it be a skin from a skin pack or one we made with the creator, if someone goes out of our render distance, their skin will change to the default Steve character. The only ways to fix this bug is to go to the dressing room and click "Edit Character" and then back out or leave the world and rejoin. Please look into fixing this bug. Thanks!
