I am having the same issue, which I posted about a few days ago. I’m trying to use pagination to have a slider in my CMS template, that can have varying numbers of slides, depending on how many images are added to the CMS item. Why blank slides appear, even if conditional visibility as added to them is beyond me…
I’ve had to use a pretty tedious workaround, involving many duplicates of the same slider, with conditional visibility on the slider itself
I really hope a solution comes about, or that this function is added in the future.
