Hello @Eggtronic,
Thanks for updating the thread. 
I think it’s because of some conflicting scripts. I tried deactivating scroll to top under theme options panel and it seems that the changes are not taking place. As it’s a live website we are not allowed to fiddle with the same. In that regards please try out the solution suggested by my colleague @basanta i.e testing for plugin conflict. I also see that you have activated minification. Please make sure under W3 total cache you have disabled minification, especially CSS and JS. X Theme assets comes pre-minified and enabling minification increases the probability of conflicts.
You can also try adding following CSS under X > Theme Options > CSS to hide scroll to top button. Please note that this will only hide the scroll to top button visually:
body .x-scroll-top.right {
display: none;
}
Thanks.
