[1.0.5] Vertical speed selected under flight directors switches to aircraft's current VS when AP turned on

Perhaps this is a quirk of the real jet, but I doubt it. I have noticed that if I am flying manually with FDs on and I command a certain vertical speed, if the aircraft has drifted away from that vertical speed when you turn the autopilot the vertical speed target switches to the aircraft's current vertical speed and you have to re-command the prior target. For an extreme example, say I have 2000 fpm commanded in the window but am doing 1000 fpm, when I turn the autopilot on the target immediately switches to 1000 fpm.

Happy to capture a video of the behavior if needed.
