Slider Issues

So I am having issues with the slider, this is the main slider under the customize section.

For some reason it has a black and green box in the bottom left section and I can’t figure out how to get rid of them.

Any idea how to fix this? Also sometimes when the slides transition they collapse up or only show 1/2 of the next slide. Does this have to do with my images?
