BMV and MPPT calibration

Hi.
I feel that my BMV is slightly off calibrated, and needs some calibration done.
Battery percentage drops 0,1 percent every 15-30 days.
Currently is charged by another brand charger while the boat is on dock, and charged by victron mppt while summer days sailing, and anchoring.
[Plans to be swapped for a Multiplus II 12V - 3000 in the future] The current charger is a "Quick SBC 501 FR" factory fitted (2011) that supplies the following:
Max output current 40 A
Charge absorption voltage 14.1 Vdc.
Charge float voltage 13.5 Vdc.
Find pictures attached for VRM portal, Victron connect BMV, Victron connect MPPT.
Batteries are U-Power TFS 250 - 12 (famous green ones)
Any help and suggestion with the settings will be appreciated.
