Item 'None' appears in inventory pls help

[Pacifier]

I would be so much appreciated if anyone could help me with this. I don't remember what action caused this when I use pkhex, but there's an item called 'None' appears in my inventory medicine tab with count as x1. The in game mart ofc won't let me sale it, and I opened the save with pkhex again, the count of all 'None's in my inventory are all zero. Even if I tried to fill the medicine tab with items which is 29 types of items in total, but that 'None' is still in the inventory (30 items in total) after launching my game. Is there a way to remove it, the item doesn't affect anything but it's very annoying. The game is Briliant Diamond by the way.

PKHeX does not support ROM Hacks that modify the savefile structure.
