Hallo @materdeo
Thank you for your feedback. It looks to me as if you are having problems with the Accessible Slick. We integrated this two months ago instead of the normal Slickslider in order to promote BFSG compliance.
To be able to analyze the issue more thoroughly, please contact us via our web support form.
