Maneuver node and travel out of Duna incorrectly shows lowered Kerbol orbit, is corrected to higher when leaving Duna SOI.

[disoculated]

 

Bug where creating a maneuver node to leave Duna that's positioned to raise the Kerbol orbit results in displaying an orbit that's lower.  After executing this maneuver and deleting the node, vehicle path also displays a destination of a lower Kerbol orbit.  When leaving the SOI, true path is displayed, which is a higher Kerbol orbit.  This looks like the maneuver node is subtracting the SOI exit velocity difference from Duna's velocity rather than adding it.

I did enter Duna's SOI on a retrogade Duna orbit, and left Duna on a prograde Duna orbit, which may have something to do with it?

Reading between the lines, I found this plotting a return to Kerbin and didn't notice the placement of the node wasn't in the right place, because the maneuver node output was showing me a direct hit on my destination.  I didn't realize anything was screwy until I exited the SOI and my picture perfect transfer became a terrible miss.
