Perfect but Mobile issue

I have looked all over and this is the first plugin that actually lets you put a custom menu on a page. The only issue is as soon as I activate it my website shows that it is not mobile friendly. When I deactivate it it says that it is mobile friendly. Is there any way you can make this plugin mobile friendly? I hated to even write this review because I think you did such a great job on this plugin but I can’t use it because of the mobile thing. I appreciate any feedback. Thank you.
