Why is the code below cited for violation of MISRA 13.6

Why is the last code line (array element initialization) in the code below being cited for 13.6 violation by Crystal Revs MISRA checker:

Code:

/*Test code for Crystal revs MISRA rule 13.6 */
typedef unsigned char uint8_t
void InitArray(void);

#define LCD_NUM_OF_COLS 2u
#define LCD_NUM_OF_ROWS    10u
uint8_t Test_Array[LCD_NUM_OF_COLS][LCD_NUM_OF_ROWS];

void InitArray(void)
    {
    uint8_t row_index = 0u;
    uint8_t col_index = 0u;    
    for (col_index = 0u; col_index < LCD_NUM_OF_COLS; col_index++)
        {
        for (row_index=0u; row_index < LCD_NUM_OF_ROWS; row_index++)    
            {
            /*    make each element of the array the char NULL    */
            Test_Array[col_index][row_index] = 0u;    
            }    
        }
    }
