CH Eclipse Yoke Elevator Issue

[theohall65]

 As you can see in the video (it's only 44 seconds long), something is seriously wrong with the elevator controls.  This worked great until this week.  Had it since May 2017.  I've done the calibration routine using the CH Control Manager, but this elevator issue now happens in both FSX and FSW.  Push forward on the yoke, release the yoke, but the elevator doesn't return to 0.  It's like he springs are sticking only when pushing the yoke forward and releasing it, which isn't fixable via software. 

Any suggestions on what to do to fix this? Can't find anything about fixing this using Google-Fu other than use software x, calibrate it using product umpty squat, or some combination of those two, which doesn't solve the issue.
