Skin change effective after a restart

I have a version of my skin that I only us during Halloween and when Halloween was over I tried changing back to my normal skin but when I select the new skin it asks me which model to use and shows the old skin and when I select model the skin does not change. I am aware that the problem is on Windows 10 as well as I have seen it in Youtube videos. After closing the game and reopening it the skin has changed but this can be an issue if you want to change skin mid-game.
