This bug encompasses doors as well. The statistic actually works with blocks placed with /setblock; even when given nbt data for which half, but it doesn't work if you /setblock a lower half and then an upper half on top (basically creating the full block), I wrote up a bug as well to include more info: https://bugs.mojang.com/browse/MC-164585
