PKMN Violet - Save not working

[Rocketomon]

I have a saved game for Pokémon Violet that I had previously modified with PKHeX to add several Pokémon. I tried modifying the save file again to add two more Pokémon, but when I try to transfer it back to the game using JKSV and start the game, it doesn’t recognize the save file and launches the game as if it were the first time. Does anyone know what could be causing this?

In the main_modif savefile I just copied an annihilape to the box 14 just to do a small change to the file but still isn't working. The main_working savefile is the one I'm using to play.

Thank you in advance.
