I’m far from an expert in this, but according to your drawings, it seems to me that strings 3 and 13 should be swapped so that each inverter is fed from strings with similar azimuths.
Your drawings show inverter 1 handling your SW facing panels with the exception of string 3, which is NW. Inverter 3 is handling the NW facing panels with the exception of string 13, which is SW. Inverter 2 is handling the SE panels and appears to function normally.
I’d try to double check the wiring to see if this is actually the case, or what.
