Importing Data into Custom Metadata Fields

Yes, csv selected and visible. numberOfColumns() no longer returns -1, so maybe I had something wrong before. I have also simplified the file to three rows and two columns:

EVENTS TAB:

app = Application("DEVONthink 3")
	app.viewerWindows()
	app.viewerWindows.byId(6481).numberOfRows()
	app.viewerWindows.byId(6481).numberOfColumns()
	app.getCellAt(app.viewerWindows.byId(6481), {row:2, column:1})
	app.getCellAt(app.viewerWindows.byId(6481), {row:2, column:2})
	app.search("name: hicks-s-2004-Explaining Postmodernism.pdf")
	app.getCellAt(app.viewerWindows.byId(6481), {row:3, column:1})
	app.getCellAt(app.viewerWindows.byId(6481), {row:3, column:2})
	app.search("name: ricoeur-p-2024-Lectures on Imagination.pdf")
Result:
undefined

REPLIES TAB:

app = Application("DEVONthink 3")
	app.viewerWindows()
		--> [app.viewerWindows.byId(6481)]
	app.viewerWindows.byId(6481).numberOfRows()
		--> 3
	app.viewerWindows.byId(6481).numberOfColumns()
		--> 2
	app.getCellAt(app.viewerWindows.byId(6481), {row:2, column:1})
		--> "hicks-s-2004-Explaining Postmodernism.pdf"
	app.getCellAt(app.viewerWindows.byId(6481), {row:2, column:2})
		--> "{ | Hicks, 2004 | | |zu:4247823:UF46F3FJ}"
	app.search("name: hicks-s-2004-Explaining Postmodernism.pdf")
		--> []
	app.getCellAt(app.viewerWindows.byId(6481), {row:3, column:1})
		--> "ricoeur-p-2024-Lectures on Imagination.pdf"
	app.getCellAt(app.viewerWindows.byId(6481), {row:3, column:2})
		--> "{ | Ricoeur, 2024 | | | zu:4247823:IWTNI9MV}"
	app.search("name: ricoeur-p-2024-Lectures on Imagination.pdf")
		--> []
Result:
undefined

I note in both cases, the first line of data (brown-d-1999…) is ignored. Is that significant?
