DC consumption is not visible on Venus GX

Hello
On the boat I have a venus GX and a Smart BMV 702 connected to a Multiplus 12/3000 and a Lifepo4 300Ah battery. The whole system worked for 6 years without any problems. After six years, the alternator snapped and the repairman disconnected it and took it in for repair. I immediately noticed that Venus does not show consumption on DC. The DC consumption on the BMV 702, however, was visible. Even when the alternator was repaired and put back together it is the same. I tried to reset everything but failed. Everything is working normally but Venus is not showing consumption on DC. The consumption is normally visible on the smart BMV702
Thanks for any ideas

Do you mean it shows 0 or the whole DC consumption tile is missing?

Settings → system setup → has DC system

yes the DC consumption shows 0 all the time, I already tried HAH DC off and back on with no success

If the BMV display is still ok, check the cabling from there to the GX.

I solve the problem
Settings→system setup→batery monitor→automatic
