Statistics in Pokedex incorrect.

[polar inlet]

The statistics for defeated in my pokedex are incorrect, and much greater than they should be. Take these two entries for Mesprit and Dialga, where defeated is greater than encountered, which shouldn't be possible.

Encountered is only Wild

Defeated counts each instance of you defeating the Pokémon, be it wild or be it from a trainer

in this case... most likely Battle Frontier. Not a bug
