Empty space on right site

Hello everyone, new to Webflow, I am encountering a problem. When I access my site, there is always a bar at the bottom for navigating from right to left, which causes the site to move instead of staying fixed. When I go all the way to the right, a white column appears, but it does not appear in my editor. I am including a photo as well as the link to the site under construction.
Thank you for your help
