I tried yesterday to land with both autopilots but I don´t know, which two are meant. But before, I tried both options but never could make both active at the same time. Yes, the ILS was caught, app mode, then pressed the second autopilot button below (CWS A) and it switched off CMD A. The same if I try to do it with CMD A and CMD B. Maybe something to fix too.

It landed fine with 1 Autopilot. Just took over throttle controll, then switched of the Autopilot and landed the plane on the last feet manually.
