Input Cupture values sometime skipped on DMA Circular mode

My environment is Nucleo-F446RE(STM32F446) with TrueSTUDIO / CubeMX on Windows 10.

I tried to get a 6MHz frequency signal by Input Capture module. However, modules often skip timer values.

/* Private user code ---------------------------------------------------------*/
/* USER CODE BEGIN 0 */
uint16_t captures[240];
void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) {
 if (htim->Channel == HAL_TIM_ACTIVE_CHANNEL_3) {
 }
}
 
void HAL_TIM_IC_CaptureHalfCpltCallback(TIM_HandleTypeDef *htim)
{
 if (htim->Channel == HAL_TIM_ACTIVE_CHANNEL_3) {
 }
}
/* USER CODE END 0 */
 
int main(void)
{
 /* USER CODE BEGIN 2 */
 HAL_TIM_IC_Start_DMA(&htim2, TIM_CHANNEL_3, captures, 120);
 /* USER CODE END 2 */
}
 

This is an example of an aquired buffer(captures[240]) on my environment. 

[825, 840, 856, 864, 2653, 2668, 2684, 2700, 4465, 4481, 4497...]

Interval between signals are should always from 10 to 20, but it has more than 2000.

This problem doesn't occur when I change DMA mode from "Circular" to "Normal". But I'm concerned about processor efficiency because a frequency of this signal is very high, 

Can I avoid this trouble about Input Capture with DMA Circular mode by modifying the program?
