Thanks for contacting us and sorry for the problem you’re facing.
Kindly could you check and confirm that each slide has a different url. You can confirm that from Theme4Press Slider > Add or Edit Slides, the go to edit page of slide and look at Slide Link. If the problem persists, kindly could you share with me temporary login credentials on a private reply so that I may dip deeper and help.
Looking forward to your reply.
