Found another issue with the picklist. If I add an item to the picklist the new item always goes immediately to the To column. If for some reason I decide to move it over to the From column and click Save, the addition is still saved to the database as a chosen picklist item.
I suspect the logic assumes any items in the additions hidden field of the form are always added to the list of picklist selections.
