Door Problems

I was doing my survival world like normal until I go into my house and notice something. The doors on the front side were backward if you put two doors together. Also zombies will not breakdown doors in hard, they walk away like they forgot you.

What should happen

Zombie breaks down door

What happens

Zombie walks away as if you were unnoticed

Also the door texture is off when you put two doors together you will notice

I did not test with iron doors just wood doors
