Quick question concerning Record locator and AY/BA?

I made a booking in J (GVA-LHR-MIA-EZE) return through aa.com and got a record locator. I hold a AY gold card...

So, when I log onto my AY account I have two different PNR's which are both copies of the original booking.

Booking PNR I: All seats have been chosen as per our wish and fed int the AA Record locator.

Booking PNR II: All seats are located randomly but are not reflected in the AA booking PNR (record locator).

Booking PNR I do not allow for choice of meal with BA through BA.com from LHR to MIA but PNR II does.

Now, I have not touched anything in PNR II as it seems like it's a shadow of PNR I tat doesn't update as one would expect it to do...

Is there anything I need to do so I don't end up with any other seats than what I initially booked/reserved? I don't really care about the meal selection and I believe the AA booking is the key here (right?) as all is feed correctly from PNR I in to the AA record locator code...?
