2-Column Slider Troubleshooting

Hey there,
I want to make a 2-column slider with images. It looks good on the first two slides — Image 2020-02-27 at 2.11.45 PM. When you click the arrow right it starts to cut some slides — Image 2020-02-27 at 2.13.09 PM.

Could you please help me with the advice on how to fix it?
Thanks in advance!

Update: I figured out this bug starting to appear because of the first slide with video. That’s pretty strange because Conditional Visibility on this slide is set to “Video > Is Set”. In my case video is not set and I don’t know why invisible slide causes the bug. Any thoughts on this?

Question #2: Is there any way to use Multi-Image CMS Field instead of Image 1, Image 2, etc. ? How to implement it?
