Although the provided solution is a little bit a dirtly-fix and the main reason that why my website is different than your demo was not found, I changed my 1 star to 5 star to support you.
And one suggestion regarding this theme:
This is really a nice theme with a really great potential however, it is a little bit slow and although I have a custom dedicated server which is powered by LiteSpeed and optimized, but your website does not load very fast. I hope that you can optimize the speed of your theme as well.
The best of luck.
