When I get near a birch door it puts me in what I think is a Spruce Wood box.

When the 0.15.0 update came out I started to notice that when I got near a birch door it wood put me in a spruce wood block but I could still move through it like it wasn't there. It only happens in certain places near the door because if I take one more step then the box disappears. My brother has it on an Android device too, and it does the same thing.
