Code P0430 catalytic converter problem

So I know for sure that my catalytic converter is broken but my car as two catalytic converters. My bank 1 readings are normal (upstream and downstream are fluctuating and stable respectively), however my bank 2 readings are both fluctuating (downstream stable sometimes but nevertheless still fluctuating when driving).

Dodge says the car has two catalytic converters, one at the front and one at the back

I'm asking if bank 2 refers to the cat at the back the car and does this mean I just need to replace the catalytic converter at the back? And leave my front catalytic converter alone?
