Fantasical Event Additon Workflow Not Setting Duration Property

I am trying to implement the Numbers spreadsheet and Keyboard Maestro workflow to add fantastical events from a list posed by Rosmary Orchard here:

My issue is with event duration. The syntax for ‘1W’ looks correct but in all cases but the first one it is entered as a one day event. I re-downloaded the spreadsheet (new copy) but that did not resolve. I would appreciate ideas. TIA.
