Classic skins reset to default skin creator skins on its own during a world or server play

This issued was encountered several times during my game play on my survival world or playing on a public server like (The Hive) ill play a few games then after 3 or 4 games my classic skins would all of sudden change on its own to the default skins made from the skin creator well i tried to fix this ill go back to select my classic skins again then play and once more it changes back to the default skins by its self again.
