Bug with the randomizer password

[Arcane Gale]

So, I've found a bug that happens when you enter a randomized save file. After playing on a randomized save file and booting up the game again later on a non-randomized save file, said save file will become partially randomized (boss rush Shelly had a Metapod, among other crazy pokemon showing up in places they shouldn't) and it stays that way until you turn the game off and then load another non-randomized save file. It's luckily not permanent, but I was kind of scared I had lost my main save file just because I used the randomizer. I do not know what causes this to happen but I will list off all the randomized options I'd had if that is somehow helpful. All three species options, first three move options, all three ability options, both item options and the last option in the "other options" menu.
