Bug starting active pokemon

HarperPGL

Playing a ranked game, I put comfey as my starting active pokemon and the game put manaphy on top of it in the active. Once it got to my turn anytime I changed my active pokemon the comfey was still there but totally inaccessible. Other active pokemon couldn't use their effects and I couldn't Retreat. The game was a total loss as I could take no game actions. Very frustrating.
