High Cell Voltage on LifePower bank

Hey everyone, I have a strange question. My system is running great, absolutely zero issues. The inverter isn't showing an alarm, and neither are the LEDs on the LifePower batteries. However, when I connected via BMS tools to check the cell balancing, each battery is showing alarm status of "Cell over voltage alarm". On the cell values (see photos), there appears to be a red line cell, I assuming indicating which cell triggered the over voltage. But they are all under 3.6, showing ~3.45. Everything seems to be working fine; reconnected the inverter comms and still no faults present. Batteries were fully charged, maybe about 400w of load at the time all handled by solar.

Any ideas is something is actually wrong? Or something I need to do?

Really appreciate the help and this forums

Note: I'm running closed loop communications, so I did have to disconnect the cable from Inverter to battery 0 (0 through 3 on the dip switches) to connect the cable to connect via BMS test.

System:
-7x 370w panels
-EG4 6500ex
-4x EG4 LifePower 48v 100A batteries in server rack
-Full off grid
