EZ Flash Omega doesn't load save

Hello,

I try to make my EZ Flash Omega load my modified .sav of Pokémon Emerald but it doesn't work.
I took the .sav from my SD Card after playing the game, edited it with PKHEX and put it back on my SD Card, writing it over the non modified one... But the flashcard keep loading the old one.

Any idea about how I can make it load my modified save file ?

Thank you in advance for you help !
