Custom Skin Reverting To "Steve" Upon Reload

When loading into the game the skin was Steve, which with an update especially a bigger one isn't any huge deal. However upon changing the skin back to the custom skin and relaunching the game, it reset directly back to Steve. It happens to any custom skin saved and from looking at the folder the custom skins are saved in within the game files, it completely empties itself once you relaunch the game. The strange part is if you reload the resource packs it’ll change them all to various Default skins and not just Steve, if you reload again however it will revert them all to Steve once again.
