Error when I attempt to modify a Nav Link image

In the Admin Panel under General > Homepage > Nav Links, I want to modify the images associated with the "You have no messages" menu, but it won't let me save once I paste in the link to my image. I get the following error each time I click the save button for that particular Nav link: "Windows Internet Explorer: You must to provide a menu name." The error doesn't even make sense.

The other Nav Links worked fine, but this one won't let me save. Even if I go into it without changing anything and click Save, I get the error.

Is there some kind of glitch perhaps for that particular Nav Link that is causing this?

Any help is appreciated.

Thanks,
Jay

yea, its kinda bug or maybe that means they not allow us to modify that menu

EDIT : i just find out what causing that bug, that bug happen only if you using IE, so to solve it just simple edit that nav link using other web browser.

e.g : Mozilla firefox

ps: hope forumation staff will aware of this bug and fix it.
