On the face of it, the conditions are met, but the odd thing I am seeing is the current goes below zero, so as soon as the batteries get up to 14.4V, they stop charging and start discharging, I have no idea if the synchronisation works if they are discharging. I can only take it that the BMS has stopped charging. In addition, the charging appears to have stopped well before you have recouped your energy.
Something is not right here. One cause could be cells going well out of balance so the charge is being stopped on high cell voltage well before the batteries are full. Hopefully you have Bluetooth BMS boards in your batteries so you can see what the cell balance is like and what is happening.
Another thought is the wiring on the shunt has been changed and is not correctly measuring. If you have changed anything then see this link for wiring. SmartShunt wiring
Finally, but hardly ever seen is the SmartShunt going out of calibration. There is a zero current calibration procedure in the manual.
Check your batteries first.
