Slimme meter

I have connected HA smart meter to P1. (Marcel Zuidwijk). Via HA I read the values ​​from produced/consumed day/night. It is strange that the 4 values ​​are not updated at the same time. Sometimes one value real-time while other values ​​are only updated after e.g. 14-25 coins. Is this a known issue or do I need to change a setting somewhere?
