Consumption == Exported

For at least the past month my Consumption and Exported values have been the same. I can select the days and have them calculate correctly but until late August this was happening automatically and correctly.
I haven’t changed anything in the way the data is uploaded, I use a Fronius push for Inverter and Metre data which has worked perfectly until August.
Is there a change in the system that i need to account for?

The system has been configured to use a Tariff Plan but the plan is not active.

Thankyou!
