Full width slider not full width

Dear technician,

I’m making a new web using Enfold and one of the demos inside (enfold one page restaurant). I’m using “full screen slider” as the first element in the content área, just like in the demo. It used to work perfect, but a few hours ago, with no reason, the full screen slider, started to show not full screen, but with a short of wide frame. I tried to change the pictures, the logo and several more things. If I place an “easy full width slider” in the first position, now, both of the sliders are full width although, there is a gap between the header and the slider. It’s really strange…

Thank you in advance for your help.
