RUT950 modbus rx max 4GB

I’ve installed it last Friday but it didn’t solve anything.
The graphical real time graphs for mobile usage are correct, although it still doesn’t show the date on any of te pages. But when looking via modbus client and querying RX the figure is different and wrong.

Today’s usage *: 21.11 GB

Modbus output: Request successful, result:

Reported in bytes, so about 3GB and not the 20 it should be.
