Female to male

Hi there!, 

i was using mixamo for the first time. i found a animation but its a female but the cover is a male. when i click on it its a female and when the cover is a female and ilcik on it its just a female. when the cover is something like a zombie than its still a female. and when i downloaded it its still a female. so how do i change female to male?
