кодчекер ожидает, что enum'ы будут is_lower

#include <stdio.h>
#define MACRO 128

enum
{
    ENUM_MACRO = 129, 
};

int main() 
{
    int abcdef = 23;
    printf("%d %d %d %d", ENUM_MACRO, MACRO, 458, abcef);
    return 0;
}

main.c(6,5): Incorrect lexema's first symbol register (is upper, but expected is lower)
main.c(6,5): Incorrect register of lexema, (upper, but expected lower)
main.c(12,27): Incorrect lexema's first symbol register (is upper, but expected is lower)
main.c(12,27): Incorrect register of lexema, (upper, but expected lower)
