are your image sizes following ‘breakpoint’ best-practices?
It appears the carousel image is ‘repeating’ itself on the largest screen size due to be being forced to fill full screen width, but it’s actual width is not large enough to do so (as seen in the safari ‘developer responsive design’ screen capture, which btw is not always a reliable rendering tool).
Perhaps this is impacting the 4-column bloc directly below it causing it to shift to the left? So, I would make sure all settings, image sizes, main containers, are all well coordinated.
