Options not showing on menu items

Good Morning

I like the concept of your plugin but unfortunately it’s not working for me. When I visit the Menu page the options from your plugin are not showing.

A copy of what I see may be seen here – https://www.evernote.com/l/AHQZSsYKBK1Dx5QwBkz7Pj11flAUjXTkxkg

I am using the Amax theme.

I welcome any suggestions. Thank you.

Peter
