[MCPE-171038] Textures will break when you try and change certain faces on custom resource packs.

I'm trying to change the top and bottom of the copper blocks for my texture pack, but when i try to, it shows the missing texture.

This doesnt make sense since i have all the required fields met for the textures to change in the first place.

This works on the other ore blocks but I'm pretty sure it doesnt work on a very large amount of blocks since I had the same issue with the Haybale.

Heres a link to the texture pack
