Batterie % perdu après update firmware

Bonjour,
My setup is 2x320 solar + 300Ah battery with Mppt 100/50, Multi 12/3000.
Just added Cerbo Gx and updated all firmware, to start fresh…
1 - i’ve now lost th Battery% that was displayed - i used VE Remote to reconfig the Multi for lithium : will it come back??

2- Should i activate VDCC ( smart shunt not yet installed) to ’ sync" the charging?
Merci!
