Cerbo Gx problems with battery

Hope someone can help
I have a victron cerbo gx, connected to it at the minute is only a victron mppt controller & a Titan lithium battery.
In the remote console its showing as is pic below, it isnt showing batt %. I think what battery info it dies have is being picked up by the mppt rather than from the battery.
As per instruction’s from Titan batteries its connected at batt end ve.can 2 & ve can 2 on the cerbo.
If I unplug the data cable it still shows the same readings .
What should I see on the remote console ?.
Could it be a faulty cable ?.
Sorry, cant seem to get the pic on here

Maybe there’s something here…

Connection type of cable type B ?
Can Bus settings in the Remote Console ?

Ve cans set at 500 as instructed off batt supplier & theysent me the cable, pinned out to their specs.

All fixed, a simple remove then reinstate power supply fixed it.
