Describe the bug

If you use a column of data type "URL", enable "Track Number of Downloads" and add a row with an http or https link, the link is properly displayed in caption but the link simply contains current page address.

To Reproduce

Steps to reproduce the behavior:

1. Add FnL to a page
2. Add a column of type "URL" and enable checkbox Track Number of Downloads.
   Save (without entering a value for caption)
3. Add a record with an URL like "http://www.github.com" and save
4. See the url properly displayed, but when you click it, it just reloads the current page.

Expected behavior

you are forwarded to the displayed page
