I too found this issue in 1.10.2, I recorded a short clip showing it. However I only experience this when dirt turns to farmland or vice-versa. Walking onto it doesn't affect me.

Tested further:
Doesn't appear to be present in 1.8, when switching to 1.8 and loading the world the sand fixes its self.
Appears to also work for walls and fence gates. Tested a variety of different blocks and only seems to be those three (Fence, Gate & Wall)
Only appears to be present when falling on blocks that are larger than one block and not smaller.
Added screenshot showing the bug is certainly present on single player.
Due to the nametag disappearing when you're not looking at the mob its difficult to show the bug. However you can see the nametag is rotated upwards went looking from a lower angle.
I have had this Issue also, Ocean Monument, Explored it with map in hand and still would not pop. Xbox, better together update. I spent literally an hour walking towards the woodland mansion and couldnt get to it and I want to get all achivemnts on one map. Annoying to say the least as this is the last one to get.
