STM32G0工程修改KEIL里的C/C++ Define定义芯片型号没有生效是为什么？

原先工程配置C/C++ Define定义芯片型号是STM32G070xx，后修改成STM32G030xx，结果编译后仍然是stm32g070xx.h头文件生效，而不是stm32g030xx.h

#if defined(STM32G071xx)
  #include "stm32g071xx.h"
#elif defined(STM32G081xx)
  #include "stm32g081xx.h"
#elif defined(STM32G070xx)
  #include "stm32g070xx.h"
#elif defined(STM32G031xx)
  #include "stm32g031xx.h"
#elif defined(STM32G041xx)
  #include "stm32g041xx.h"
#elif defined(STM32G030xx)
  #include "stm32g030xx.h"
#else
#error "Please select first the target STM32G0xx device used in your application (in stm32g0xx.h file)"
#endif
