BxSlider WP Pro – Carousel Options not functioning

I purchased the BxSlider WP Pro version to utilize the Carousel Options, which should allow for a slider to display multiple slides at one time. I installed the plugin by uploading the .zip folder provided during my purchase, which made the Pro Option tabs available for editing. However, any changes to the Pro Version tabs (Pager Options, Controls Options, Auto Options, Carousel Options) do not affect any of the sliders.

How can I get the Pro Version Options to be applied to my sliders?

Thanks.
