Featured Image Duplicated in "Categories"

Good afternoon.

I′ve been having problems with the “Featured Image” with the Theme “MH Magazine Lite” (last version).

At first it appeared duplicated in the single post page, but thanks to a post in this forum, I resolved it.

Now i’m having trouble because in the “Categories”, you can see the featured image duplicated and at the top of the page…

Can anyone lend me a hand? I′ve been looking but here are files that don′t appear in my site, maybe because in the forum they have an older version.

Thanks…
