Smart meter reading

I am trying to enter my 5 digit smart meter electricity reading but the system is requesting two readings, day and night. How do I change the meter reading entry screen to imput just one line??

Hi, there is a guide on how to do this here http://support.bulb.co.uk/customer/portal/articles/2805466-how-do-i-read-my-meter-
For smart meters you usually press the number 6 to see a rate 01 and a rate 02.
