Single post in PokéDex errors

I had converted Gengar to it meaga form, and started wondering what mega forms I needed. I search my pokedex for Gengar and good not find a mega form listing of it. So it started looking through the Pokedex and found the group 'PokéFarm Q (Megas)'. When I look though it Gendar is missing from the Megas section - looks like it needs to be added to PokéFarm Q (Megas).
