Incidental expenses simplified arrangements on importing

Hello. I have just had the paperwork for some imports of goods. The clearance agent has included on the paperwork two incidental expenses for VAT calculation. They have used method 1, actual costs and method 2 national agreed rates. I therefore have VAT on method 1 actual costs of £156 and method 2 £170. When looking at the guidance only 1 method should be used as per Incidental expenses — simplified arrangements I have contacted the clearing agent and they have advised they need both included. I believe this to be incorrect. Can anyone advise. Thank you.
