Game won't load the edited fils

[0hro]

I'm new to PKHeX, so i used PKHeX to add a few pokemon to my Pokemon Sword save files, then after starting up the game on RyujinX, it's still back to when it was not edited, i don't know whether the save file which i replaced is the main save file or there's more file, so please tell me what i did wrong (Sorry for bad english)
