Last 3 icons link to javascript: void()

I recently noticed an extra ‘http://’ on the final icon all the way to the right on my site staged here. I went into the settings and updated the URL for that icon, yet when I saved it, that item and the 2 icons to it’s left (Google Map & Yelp) suddenly changed their links to point to “javascript: void();”. In the settings, those items are showing the correct URLs, so I can’t understand why they aren’t updating.
