www.remarpro.com site ” Menu” background

Hello, I would like to address this query to anyone who can help resolve this issue. I’m from Japan, and as I view the www.remarpro.com site, I notice that the background in the menu view is blocking some of the components in the site that hinders us from viewing the content.

Please if you can fix it.

Thank you very much.
