Cannot add data in old custom fields

I upgraded a few weeks ago to the Responsive directory theme.

I added a custom field (see screen shot attached) when I upgraded. I cannot add text/data to the customs fields that I had previously created.

I tried to create new custom fields in the Listings Manager using same db keys but it displays duplicates (for example – it will show 2 fax and 2 websites). I tried to delete the old custom db keys via the CSV but when I re-import the CSV I get an error (UTF-8..)

What can I do to allow me to edit cusomt fields)?
