Fusion Directory search doesn’t work

Content

Hello , 

When clicking on the search it doesn’t bring up anything - meaning as if the search doesn’t work. (the outside search) 
When clicking in the directory in navigation -> entering a name of an employee- the search work. 
But the search inside the search area ,once getting in the directory screen - doesn’t work. 

What could be the reason ? 

see sceenshots attached . 

Thanks
