Customizr Theme Menu Dropdown Malfunction

I have a dropdown menu from one of my menu items in Customizr theme, and the drop-down options are hidden by the featured image on the home page. I have a screenshot, but I don’t know of a way to upload it to the forum. Basically, Customizr has those three featured pages at the top of the home page, below the header menu. Each featured page has a featured image that – when your mouse hovers over it – expands to show the full image. But with this dropdown menu, it’s dropping down behind the frame of those feature images, like the code is messed up.
