SmartBMV 712 won't auto sync

I am using a Color Control and a SmartBMV 712. I have 2x200ah lifePO 48v batteries. I have been at 100% SOC according to my battery SOC indicator a number of times, but the 712 is not synchronizing and showing 100%. I've done several manual resets with no luck. I have sst my charged voltage as low as 53.2 (and SOC exceeded that multiple times) without synchronizing. discharge floor is 0%, tail current 4.5%, charged detection time 1m, P exp 1.05, charge efficiency factor 99%, current threshold 0.10A.

Does anyone have any thoughts? I am brand new to Victron gear. I like the technology and performance but I am struggling with lack of easy to use step-by-step documentation. Any help would be appreciated a whole lot!

I forgot to mention, the VRM Portal shows I am net charging the batteries with excess A's from the charge controller but the BMV still shows "-16.00" on the current.

Is the BMV wired correctly?

This "battery SOC indicator" is the battery BMS?
