Menu pops up under footer

Hey guys, great theme and as I can see great support! Congrats! I have a small but very annoying problem with the catch fire theme, whenever I refresh my site, a weird menu pops up under the copyright area and dissappears when the page loads completely. For some reason I can't embed the image so here is a link: http://imgur.com/p5bQqHN This occurs either in mobile and desktop environment. Tried ro switch to Catch Fire (im using child theme) with almost no custom CSS but no luck so far. Any help will be appreciated. Site address is http://www.savchev.bg
