Wintix seating plans are comprised of a grid of cells. The seating plan uses whatever has been put into the farthest left cell of the row to display as the row indicator. If you don’t put anything in that cell, the row indicator will not display. As some rows are trimmed down and don’t have a seat in the farthest left cell, you need make sure that data for the row is entered. Click on the cell and type in the row number or letter. Close Wintix. Reopen it and you will then see it displayed.
