Hello,
Please download the development version of the plugin from this link https://iptms.co/fsqmdev3b1 and install as usual. This is a known compatibility issue that is happening with many themes and plugins because most of them use a very backdated jQuery Waypoints Library.
While using the given copy will resolve your issue, I recommend contacting your plugin developer Visual Composer to update jQuery Waypoints.
