If nothing (no buttons or anything) is showing, please make sure you've set the "Menu" options to "Show all" so that it shows in all areas of your site, instead of "None" which is the default.
If something is showing, please make sure you've enabled the "Include jQuery" and "Include Bootstrap" setting (if shown) in the options.
If none of that helps, let me know a URL where we can see where you configured the module and we'll gladly help investigate further.
Thanks,
Alex
