Kenta Slider: Only one possible per page?

Hi,

I added the Kenta theme and it comes along with a slider block which I like to use. But here’s the catch:
If I use two sliders, they act as if it was one. Only the prev/next arrows in the first slider works, but it slides actually the second one.

Does somebody know if this is a limitation or a bug? Does somebody know an alternative slider that works just fine?

I don’t use the premium version (as it’s not documented that this will resolve the issue) and the slides are limited to 4 per slider as documentation.
