Wordpress plugin scroll and background

Hi
I need some help!
I use the plugin for wordpress to implement the shop in my webpage.
I have problem with the web scroll down it’s not working when the screen is maximized in chrome and firefox. The screen stays fixed, how can I fix it?
In the explorer works fine and if I minimize the window and resize it it works properly!

This is the web https://texelgames.com/this-is-the-oficial-texel-games-t-shirt-and-complements-shop/#!/

Thanks in advance!
