[Plugin: Mobile theme switch] Switcher working but still loading header/footer from desktop theme

Plugin started out working like a charm but now I’m running in to issues. When I look at the mobile version of the site, it’s loading content from both of the header and footer files (desktop and mobile) – not ideal. On top of that, no styles are being applied. Any clue as to what might be going on?
