Display module configuration

We are running a version 1.5.4 business on a test server which has been continually upgraded from 1.0.0. I believe this issue was present in previous versions. I have looked at the demo shop and the issue doesn't appear to be present.

In the shop we go to the back end enter the configuration page, choosing the display tab. In the box > General display option there is the entry Modules under the product page. Even though no module has been select we have : Options for the ''. We have tried clicking on "select" making sure nothing is selected, click on okay then save the configuration settings but it still remains.

How can we remove this?

This is just a display issue on the config page.
If you change the code:
if(!empty($element)){
to:
if(!empty($element->title)){

in the file "display" of the view "config" via Display->Views (for your back end template) that empty link will disappear.

we had the same problem in views > menus > form.php in line 169. Changing:
if(!empty($element)){
to:
if(!empty($element->title)){
