Can you delete the whole thing, insert a blank measure and reenter the notes?

What I would do:

1) Make a backup copy of the document, and open the backup copy.

If something goes wrong with the backup copy, you still have the original copy.

2) In the backup copy, switch to Scroll View, and examine that measure in Scroll View.

You can use the dialog box Staff Usage in Scroll View.

3) When the staff spacing is fine in Scroll View, switch back to Page View, and use

Staff menu > Respace Staves…

Choose the option {Set to Scroll View Spacing}.

This step should fix the entire document.

4) If that does not fix the problem, switch to the Page Layout Tool, and try

Page Layout menu > Redefine Pages > …

Neither of your suggestions worked:

1.  When I delete the measure, the problem rolls to what was the next measure.  When I re-insert a blank measure, the problem transfers to the new measure.  It's as if the problem is in one physical location and anything there becomes another creature.

2.  The measure looks perfectly fine in scroll view (see left measure below).  There's nothing to see.  When I go back to page view after doing the Scroll view spacing choice, it's still there.

Any other ideas?

Did you also try

Page Layout menu > Redefine Pages > …

?

Yes, all that did is make this nicely spaced, but kept the overlapping measure intact.

Since we are grasping at straws here, try exporting the music as XML and then importing it to a new Finale document.
