From what I can infer, the standard default display that scrolls through the four screens shows total kWh consumption, which is simple enough if the meter is configured as single rate (non Economy 7). It shows total kWh recorded. Your initial post stated the display was showing 59 kWh, and your later photo shows 37.24 and 44.51 which adds up to 81.75. With electric heating and hot water, the difference of about 22kWh over a day or so sounds about right to me.
If you look at the standard display now, I would expect that figure of 59 to have gone up to the total of the two rates. If so, all is well in your world 👍
Also note that it's not just about heating or hot water. All electricity you use anywhere during the off-peak period is charged at the lower rate. When I had Economy 7, back in the day, and an old fashioned washing machine and tumble drier with electro-mechanical timer/program controls, I had plug in timers for both, so that I could load them up before bed, and they would then power up and do their thing when the timer kicked in. Not so easy these days with more modern appliances that need a button pressing to start them.
I was a bit of a night owl anyway and my adjoining neighbours were a way a lot, so I even did my hoovering after midnight to maximise the savings!
I'm not suggesting you have to stay up past the witching hour to do your laundry, but I know folks that do. A friend of mine even preps batch meals earlier in the evening and then only puts the oven on at off-peak rates. But he is a native Welshman, so even tighter than me and that's saying something 😉
