Footer Widgets in Mobile overlapped on Frontpage

hi,

im using the zenon lite template on my wp. so on mobile view the footer widgets overlapped, but only on the frontpage – have a look at it: https://www.responsinator.com/?url=www.rudolf-mundt.de%2F (sometimes you have to go to a second site and then back to the frontpage, then you see the false)

can anyone help?
