I've helped correct a issues that several people have had with FSUIPC / P3D thrust lever setups. I realize part of this may not make sense, but give this a try:
1. Rename, or cut and paste your FSUIPC.cfg file so that it is no longer recognized by FSUIPC.
2. Start P3D and remove and reassign the thrust levels, do not change the calibration settings, and then test in the aircraft.
3. If you wish to have to use FSUIPC for the Airbus (not our recommendation), then first remove the P3D control bindings, close and restart P3D, and then close P3D again. Then restart P3D and rebind the Airbus controls in FSUIPC.
4. Close P3D, copy and past non-Airbus aircraft entries from your previous FSUIPC.cfg file to the new FSUIPC.cfg, except of course for the newly created FSUIPC Airbus bindings.
Let us know how you make out.
