interaction with date field is confusing

• Tooltip uses a different date format than the field, though the tooltip date format is accepted and converted automagically to the field format. Especially confusing because the field description isn’t shown completely (Month/Day/Year)
• Filling in an incomplete date followed by shifting focus to a different part of the website results in loss of data (field goes blank)
