Issue with "back-to-top" button

Hi guys

Thanks for the great theme. I'm like 99% finnished with the website, but all of a sudden an issue came up and I just can't seem to figure out how to fix it.

The back-to-the top bitton looks odd even thou I never altered its look. At the same time for some reason there is an "X"diplaying between the footer and the last content block. See the image below:

Do you have any idea how I could fix this? This is what I see in the code.

Perhaps this piece of code could help you?

Thnak you in advance
