What you have looks right. What type of field is 'quantity_uom' can it be null? If so then you need a null item in your list that is hidden.

Whatever the database field "quantity_uom" is returning in the item being edited is not one of the values: D, T, Y, G.  It might be a null or empty value coming from the database, in which case doing an ISNULL on the query might help:  ISNULL(quantity_uom, -1) AS quantity_uom ...
