The icons look ok to me ( sun for day, moon for night).
My meter gives readings in following order:
Rate 1 night
Rate 4 day
I then have to enter against the relevant description and icon which has always been in reverse order (but correct entry)
However referring back to your original posts I think you mean your day and night readings that you have entered have swapped.
I can’t help with the readings being swapped, however :
Again referring back to your original post, something which I missed, you are apparently using more day units than night. This is not good, the day rate is more expensive, economy 7 meters are meant for users who have a high night time demand when there is traditionally often cheaper / surplus electricity. Traditionally these meters are fitted when electric storage heaters are in use for heating. Nowadays it can also be used for charging electric cars.
As you apparently are using more day units, once you have sorted the swapped readings it would be beneficial to have the meter replaced and go for a standard single rate tariff.
