Retroarch 1.8.4 cheats not working any help

Hello everyone I’m using retroarch 1.8.4 on a nintendo wii u. I have gone to online updater and downloaded cheats. On the PC program of retroarch to pass to the wii u. After loading a gba game uaing the GBA core for example dragon ball advance adventure and tried to enable cheat.

Making sure must be on cheat is enable then choosing a cheat and applying changes. Returning to the game or restarting the game after cheats have been enable I see the it reads on the bottom the cheats have been applied but when the game starts the cheats dont work. Any way to fixed this?
