DCS 2.2 Su-25t Autopilot Alt -3 flies me into the ground

Hi,

Pretty new to DCS World. Everything in 1.58 works fine. But in DCS 2.2 when I'm in my SU-25T, and I use Alt-3 for straight and level flight, sometimes the plane will dive and level out about 50' above the ground. Most times it just dives straight into the ground.

This does not happen ever in 1.58. In 1.58 pressing Alt-3 causes the plane to lock the current altitude and level the wings.

Thanks,

Robert
