No Power Usage Registering

Hi I have connected a smart monitor 712 to 2 x 225v lead batteries in my camper van. I have double checked and it is wired to the shunt correctly. I'm getting no reading of consumed ah and the time remaining is on infinte no matter what the drain.

Sometimes it needs a charge cycle or two (depending on DOD) to settle down.

FYI lead acids are more like 85% efficient on charge. You posted a day ago has there been a change?
