Pokemon Crystal : How to reset pokedex "Pokemon Seen" number ?

[Asia81]

I was playing arround with cheat codes and I encountered a corrupted pokemon that looks like missingno, and it increased the number of Pokemon Seen in my pokedex.
I tried with PKHeX to reset Seen and Caught to None, but it still at 1 Seen for 0 Caught

Any ideas that is not starting a new savefile ?

Seen count in block data is at 0 but in game pokedex still say 1
