Electricity Meter Readings : Only one reading on my meter

Hi, just signed up to Bulb, and needed to submit meter readings. The electricity meter readings ask for a “daytime reading” and an “evening reading” but my meter only shows me one number. Am I missing something? I read the article on submitting meter readings on the bulb site, but that didn’t address this query. Thank you in advance for your help :-)!

Hi Manas, please can you email a picture of the meter to help@bulb.co.uk.

Thanks
James
