[Switching between pokemon error]

I just started playing this game. and i got this bug on every battle with 2 or more pokemon. After i faint the first pokemon, i get this error.  After i click ok, i get this battle scene with no opponent pokemon. If i use a move, it says no pokemon is there and then the battle continues properly. Has other people also gotten this? How do you solve this?
