No Textbox Area for My Listing Fields

I’ve problem with my listing fields after converted my site from DT v7.1.3 to Responsive 6.6.3 recently.

I can’t key in the details as there are no textbox area for my listing fields such as :

1. Address
2. Contact No
3. Business Hours
4. Contact Person

Would appreciate any assistance to call out the textbox.

Is it possible to delete these fields so that I can create my own customized fields?

Thank you.
