I had to export as Batch is too taxing to run on my site.
In BBEdit (Mac text editor) used the search “2 PLAC .*,$ >>> no brackets and found 2 PLAC Ostrowitz, Plzeňský Kraj, Czech Republic,. I recognized this as one I just changed (GUI) and obviously didn’t know I left a comma behind.
I then noted the INDI number and went to that record and made the change.
Did a display for Place hierarchy and “unknown” is gone. Thanks.
