I am using X-CUBE-EEPROM_V2.0.0 and encountered a write failure problem

[Bence]

​I can read and write normally after using the EE_Init(EE_FORCED_ERASE) function to initialize. But when I use the J-Flash tool to read back all the contents of the flash and save it as a .bin file, then erase the flash and download the saved bin file to the flash, I found that the program cannot write data normally.If anyone understands this situation, please help explain what the problem is？
