Featured Slider??

Hi..I like this CatchFlames theme but I am having some issues here. 1-I am unable to setup featured page slider.For this slider, if I add a page with a featured image then the page title shows in the home page menu which doesn't look good because I don't want to change my menu. However if I add a post with a featured image then I am unable to select that post from the Appearance=>> theme options => Featured Slider =>> Featured Page Slider Options. 2- For the about us page on my website, I want a featured image but this featured image doesn't turn out to be full width. It becomes a 2-column layout and I don't want that.
