New installation, strange VRM numbers

Hi everybody.
I've completed my new Victron installation, and while everything is working, the numbers in VRM are looking strange.

Take a look at the supplied screenshots. One is with the inverter turned off, the other with the inverter turned on. With the inverter off, the numbers make sense, the DC load is 6W which is consistent with the power usage of the Cerbo.

But when I turn the inverter on, the DC power goes to negative 29W, why is that?

My system:
Cerbo GX
Multiplus-II 24/3000, connected to Cerbo with VE.Bus
2 x SmartSolar MPPT 150/35, connected to Cerbo with VE.direct
SmartShunt 500A, connected to Cerbo with VE.direct
Orion-TR 24/12-20, currently turned off
2 x 24V 100Ah Lithium batteries, connected in parallell.


Settings in Cerbo:
Has DC system = on
DVCC = off
ESS = off


VRM

The multi has a standby current, this comes from the batteries and is what you're seeing
