Item glitches while using certain Classic Star Wars skins

So, I was playing Minecraft on my Xbox with two controllers (I was switching back and forth to do things like test out enchanted weapons, you may need to know this because it might only apply to creative mode and multiplayer). Well, I had bought the Star Wars Classic skin pack a while ago. Now, I had played AstroLink Survival as Fett and did not experience glitches (well, yeah, his jetpack disappears when you wear Elytra, but that's not the bug I am reporting). I even played multiplayer without a problem (that time a friend was playing with me using the same secondary account). I created a superflat world later on which is what I was playing with two controllers. What happened was this: when I tried to switch inventory slots, the game would rapidly switch my hand item back and forth until I pressed the button again, in which case it would either skip the item I wanted, select an item on the other side of the hotbar, or rarely (slightly more commonly after several tries) actually land on the item I wanted. I tried to enchant a bow with an anvil and it DELETED THE BOW AS SOON AS I PUT IT IN THE SLOT. AND THE ENCHANTED BOOK. I had to use the secondary account, who was using the "Luke Skywalker, Bespin" skin, to enchant the bow. Everything was fine when I switched to the Yoda skin (SEAGULLS!!) later on. The glitches came back when I changed back to Boba Fett. Please fix this issue. Boba Fest is my favorite Star Wars character and I don't want to have to choose between a reasonable game experience and playing as the character.

UPDATE: I got rid of the extra player and the glitches continued.

UPDATE 2: I also experienced a more minor version of this glitch with the Jawa skin.
