Hi @Mark_Goudie
Thanks for posting about this!
At this time the slider isn’t fully dynamic. That is to say, you can add it to a collection page or list and binding images to the slides, but it’s not natively dynamic so it has some odd side effects. One such side effect is the last slide / mask that appears at the end.
We have an internal enhancement request filed to create dynamic components but I don’t have a definitive timeline as to when we’ll ship that.
For now, I recommend building out a dynamic slider using a bit of custom code. One of our community members made a great tutorial here: Creating a Dynamic Slider in Webflow
