Axpert Mecer Inverter and 5.12kwh Shoto SOC

My Axpert Mecer 5KW inverter is connected to a Shoto 5.12kwh (16s) lithium battery. This is setup purely as a backup system - no solar.

The inverter and battery BMS are monitored via Solar Assistant. 

I have the following battery settings enabled on the inverter:

I'm encountering a phenomenon where the grid charges the battery to only 96% state of charge (SOC). Following this, the battery gradually discharges to reach the float charge voltage. Several hours later, the SOC percentage begins to decrease gradually and continues to fall over the course of several days. I would greatly appreciate any insights into the possible reasons for this and any advice on how to address the problem.
