How can I duplicate multiple fields?

I am selecting multiple fields. 

I then select the duplicate button and get shown this:

I select the "After Field" option - but I don't see where the duplicates are appearing. 

Any ideas?

Can you share with us the form and what fields are you trying to duplicate then after what specific field? For duplicating fields, this guide should help you: https://www.jotform.com/help/242-How-to-Manage-Multiple-Fields.
