Stretched Sections becoming unstretched while navigating around site.

Hi! I found an odd Elementor bug. All the sections on my home page are stretched, but when I go and click on an individual page, e.g staff, and then click back to my homepage, the sections have become unstretched and the video in the bottom section is gone. I would be grateful if anyone had any clever ideas on how to resolve this. : )
