I’m seeing the same thing. I’m also seeing that the Finder windows for many of my folders have more than one name column (according to AppleScript)! In one case:
tell application "Finder"
tell front Finder window
tell its list view options
name of columns
end tell
end tell
end tell
--> {name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, name column, modification date column, creation date column, size column, kind column, label column, version column, comment column}
Also, the Finder’s AppleScript implementation doesn’t recognise Date Added or iCloud Status columns. It looks like a bug (or several). More likely, given past and ongoing performance, someone at Apple can’t be bothered to update the Finder’s scripting implementation.
