Can’t make Home page full-width

In the Enigma theme, I have the Homepage settings set to display a static page. In the settings for each page (including the Home page) I have selected the “Full-width” template (so that the page takes up 100% of the available main-content area – instead of leaving space where the sidebar would typically appear on the right). I cannot get the static page to display full-width (like the rest of the pages in my site). Is there some setting I can adjust, or some PHP I can edit, to fix that?
