Can't Change Clothes After Changing Player Gender in Shield

[Hammertime64]

So I used PkHeX to change the gender of my character to the girl character. To do this, I imported the *Object MyStatus block from a girl save file from a different profile, and then I imported the complete *Object Fashion block that I got from here. After loading the game, it has the girl character, but she is stuck wearing the Gym Challenge outfit (with no backpack). Trying to change clothes shows the game thinks I have a different outfit on (the green check marks are on different items, and reprinting the league card shows the right outfit), but isn't showing it. Also, when I try to change hair, it works, but in that menu the character model is T-posing and has no face so I think there's an issue there somewhere. Changing makeup works fine as suggested by other threads I've seen, but it doesn't do anything to allow me to change the player's clothes. Has anyone encountered this before?
