Charge controllers
I'm a fulltimer and my 2017 5er is almost always hooked up to shore power. I have 2 12v batteries. I 'believe' one is strictly for the inverter circuit (residential frig and possibly WH). The other ba...

Your converter is probably ok.
You are allowed to have an "inverter battery bank" and a separate "regular loads RV battery bank". They will run down and need recharging at different times. They need to be recharged individually.
You are also allowed to have all your batteries in one bank with the inverter as just one of the "12v" loads along with the furnace, lights, etc. That bank can be recharged all at once with the converter or some other charger or by several chargers at once.
You seem to have the two 12s in parallel via the combiner for recharging, but have the inverter load on one and the rest of the loads on the other. This is called "tapping" and is not good. You are getting one batt way down before the other and it is confusing your system.
Best way is to take all the load wires off the battery posts and just leave the combiner ones on them so they are still in parallel for recharging. Now put all the load wires on the input (converter) side of the combiner. Now all the batts will draw down together and not confuse your system. Recharge them together off grid with the converter using your gen.
If on shore power, just leave it all be as rewired, and it should work fine with the two batts in parallel "floating" off the converter.
