Fixed slicknav_menu disables scrolling pages

[psychome]

Hi. For my one page site I have implemented srolld.js (http://scrolldjs.com/) in order to show graceful scrolling pages. However, if I set slicknav_menu position as fixed (and I need to do that) scrolld does no longer work. It seems a conflict of the two plugins. Is there a work around for this problem?

Thanks.
