Woodland Mansions not generating correctly

I found a Mansion via a woodland map in my world and it was broken. I thought maybe it was just a generation error, so I started a new world, used locate and teleported a few hundred blocks away and flew over and it was broken in the same manner. Not sure if this affects any snapshots before this one, as I never went to any Mansions. First screenshots are the same world, last one is a new world.
