Mx mega menu problems on mobile devices

I have used the free max mega plugin to create a top header and header menu on our website.
But it really looks bad on mobile devices.

… uneaven menu.. different hight and color.

We use the beaver builder theme.

The website is called suresms.com

I can send you long in info if needed

Best regards,

Lone
