LTO demerit points need help!!

Nagka violation ako for driving an unregistered vehicle and not wearing a seatbelt which is equal to 6 demerit points, i need help to clarify LTO's rules.

  1. It is stated na if a driver have atleast 5 demerit points, mandated ang driver to take DRC.

  2. If driver accumulated 10 points required si driver to take DRC

Hindi ba overlapping yung rules nila?

If 5 ang minimum for taking DRC bakit wala akong nareceive na notification from LTO and worried ako sa isang statement nila na dapat makapag take ng DRC within 30 days from last apprehension or face suspension of driver's license.
