Generator input and a load not showing when generator is running

We have a Multiplus II, Cerbo GX, Smart Solar and a Honda 6500 sx generator.

When we run the generator, the Cerbo display changes load to - - - Nad also the same - - - for generator.

It used to work fine, but a worker ran a tablesaw. Should have been fine, the generator was running, the saw uses 3000 watts start up and 1600 to run. The GFCI on the generator tripped though. We reset the GFCI, and now the display on the Cerbo is all. messes up as described.

We see wtts going in to the battery, but seems like they are not being managed by the Cerbo /Multiplus.

We have powered the Multiplus on and off, reset all the breakers, even sut down the entire system including batteries with no effect.

Any suggestions?
