Feedback on this Wordpress Template Axiomthemes pleace help me

We will work on a wordpress theme from our Envato account, we encountered a problem after installing the theme and installing demo content. The theme does not scroll down the page in browsers on Windows computers, the home page is stuck on the home screen, and while the browser can be downloaded with the side scroll bar, it jumps up again when you touch the mouse wheel. This problem was not seen on the inner pages.
When we tested the problem on Macbook computers, it worked fine. This problem has been tried on different browsers and different windows computers and gets stuck in all.
