Had this same problem, and fixed it
1. Make sure your NDS Cartridge Backup media is: Flash 512Kbytes (apparently you are)
2. It seems that this problem only occurs when you play the game using myZoom. When i used it with normal No$GBA or with NDS2xGL2 the save worked.
So your gonna have to play with either default or NDS2 unless someone finds another solution. Also when closing the program, actually go to File>Quit/Exit.
I hope i helped
