There is an issue is that numerical values are shown in ascending order under the Asset picklist additional field.
If a user complains about this specific issue, it is because Pick List values are stored as string in the database, so the fields are being rendered in the form based on string-based sorting.
So instead of using 1,2,3,4,5,6,7,8,9,10,
we can suggest this 01,02,03,04,05,06,07,08,09,10,
