C450 stop adjustment not working

I installed a C450 for a friend's mom.

I need the door to stop at the top, about eight inches short of the full throw.  I have read the manual and watched the video on how to adjust the stop point.  Press the center button.  Use the arrow to set where you want it to stop at the top.  Press to adjust bottom, if necessary.  Push again to set.  Lights blink and relay clicks.  Very simple

Then, I test.  It ignores my stop point and runs all the way to where it hits a physical stop.  Bang!

I went through the process multiple times.  I watched the video, again.

I'm at a loss.  Does anyone have any suggestions on how to troubleshoot this?
