Stage Seperation Leaves Control of Unmanned Rocket Engine

[KSPXplorer]

So when I activate the decoupler my command pod and science lab seperate but camera and control stays with Rocket engine and fuel tanks.  This happened after I restored a quicksave.  It has also happened in the past after I reverted to the launch pad.  I am sure there is a simple fix (I hope) but not seeing any key commands that transfer controls from one unit while in flight.  Please help and thank you.

Use the [ and ] keys to switch between vessels close together. You can avoid this altogether by having the root part in your payload.

Or L1/R1 + Left/Right if you're playing on PS4. Probably LB/RB + Left/Right on Xbone.
