When attempting to change between custom skins, it won't change to the skin selected until Minecraft is closed and restarted.

I was attempting to view two different custom skins I had created when it wouldn't change to the second. I, unfortunately, am having issues uploading the screenshots, but I will try my best to explain. I already have Custom Skin 1 on, and when I attempt to change to Custom Skin 2, it still gives me the option of whether or not Custom Skin 1 should be the Alex or Steve model. (Arm pixel width) It should be asking this about Custom Skin 2, but the image is Custom Skin 1. However, when I close and restart the game, Custom Skin 2 appears as the skin I am wearing. This can be recreated by trying to change from one custom skin to another. No mods, resource or texture packs were in use. I tried and received the same result when in-game as changing skin in the menu screen upon first opening Minecraft. Thank you for reading my incredibly long description for this bug.
