Hi lawrosa,
Yes when you plug into shore power the converter powers the house loads and recharges the battery bank. If the shore power fails, the twelve volt devices are then powered by the battery bank.
But, with an inverter running a converter, the inverter is drawing from the battery bank. It will power the house loads and attempt to charge the battery. I.E. a loop where the converter tries to charge the battery by drawing power from that same battery via the inverter.

The only way to use the converter to power the 12 volt side of the house is to make sure the batteries are disconnected from the 12 volt "house" loads, with only the converter powering the "house". It is quite inefficient, with a 10% loss at the inverter and as much as another 30% loss at the converter
When you plug into shore power does the convertor make the 12 volts for lights and such?
