Batch update via Profile - copy icon fails for fields of 'select' type

1. Create custom data for a Contact which contains a field with format 'select'
2. Create a profile that displays that field
3. On the results of a contact search, select the 'Batch update via Profile' task and the Profile just created
4. Fill in the field for the first row and press the Copy Icon, to reproduce that value in subsequent rows
