A couple of troubles

I bought the Universe theme a little while ago and have some troubles with it.
My website is www.thetomelegend.com

At the moment the two I'm wrestling with are
- The Facebook Share button isn't showing when turned on.
- The layout is not working that well on mobile devices. I check it on android mobile phone and the top slider bar appears slightly greyed and is overlapping the first silver divider bar.

Thanks for any help.

Hi!

Could you show the screnshot what does look wrong in the mobile view, please.
Perhaps, you need to turn on Social buttons to see the Facebook button. You may do it on the page Universe --> Social Buttons.
