Once you edit a field template, you can no longer leave it blank.

If you try to leave it blank, you will get this error message:

"You must enter a value for itemtemplate. Please click your browser's back button and enter something for itemtemplate."

If you really want to leave the template blank, you can enter an empty [HTML] tag, such as
<a></a>
