Armor and elytra glitch

The armor should be like in IMAGE 1 

But it is like in IMAGE 2 in my world and the armor in IMAGE 1 is unenchated and in IMAGE 2 it is enchanted 

In IMAGE 3 i had equipped elytra but as you can it seems as there is no elytra and this glitch comes in every new world i create.
