Bug with trainer card (FireRed)

[TetsuyaGR]

Hey guys, i as i was playing my firered i went to my trainer card and i noticed an azumarill there but i don't even have one! I wanted to know if someone knows the save offset for the 6 pokemon slots in the trainer card so i can check if my save is bugged or something because i really wanted to play a legit with no cheats gameplay and after pouring so much time into this save i notice this bug  (I know that i can just go to the game corner and put some other pokemons but i would like these slots to be empty)
