Webflow Slider merging slides 2 & 3 into one

Is there any logic to how the slider combines slides when a mask is resized? I was pretty sure I could build this slider with stacking cards, but I cannot figure out how to keep the Slider from combining slides 2 & 3.

It registers all 4 in the designer, but once the Interactions resize the slides on the live page, it reads it as 3. Incredibly frustrating. Makes no sense. I’ve never wanted Webflow to group slides… I don’t know why that’s even a thing.
