lot setting issue for me , anyone else??

[schnorchel]

latest patch 1.00.13954 is installed,
I disabled the steam cloud firstly.

1.can not turn cockpit off.
I unchecked the cockpit always on in realism setting. and set the contrl+F1 to toggle it. but I can never turn it off????

2. auto pilot (toggle AI control)
does not work(I only fly in QMB)
3. horizontal stabilizer
does not work (I only tried on JU8
4. realistic gunnery.
I am sure check it in realism setup. but seems from whatever postion i attack the enemy if I take any lead for deflection shoot I will miss it unless I just put the centre of crosshair to the target.
