Text/Value is set programmatically on spreadsheet load, but text does not show in cell until double-click on the cell. Formula bar shows text value when cell is selected.
On a side note: Right clicking a cell, and selecting "Define Name..." throws an error: System.NullReferenceException: 'Object reference not set to an instance of an object.'
