Pro Version with multiple carousel sliders wrong arrows

I bought the PRO version and use the “Showcase Carousel” with 2 sliders on one page. Both sliders have different CSS IDs. On second slider no arrows appear and arrows of first slider does slide the second slider elements.

If I deactivate “Showcase Carousel” everything works fine. Both sliders have arrows and arrows work for the slider they appear.

But I need more sliders with “Showcase Carousel” working on one page.
