I did try to collapse & expand all nodes & that didn't help, as the county didn't have anything under it.
But I fix it:
Before I closed FTM, I renamed the auto backup file, so that if necessary I could go back to the day before & only loose 1 day of work, but still have place names. So I wasn't worried about messing anything else up in my 'real' file, so I clicked the icon for 'show place names as a flat list' at the top of place names & my missing places were there. When I clicked 'collapse all nodes' & then 'expand all nodes', there were back where they belong :)
But for some reason, is shows 'Houghton County' when listed as a county vs Houghton (the city) listed below. as you can see by the attached pic no other county lists the word county, even others that share a name with a city/village.
that is what I was trying to fix when the places went away, so I can live with it, just wondering why.
Thanks again for all your help,
