Hello,
Issue seems to be due to the scroll bar at the right side.
Suggested solution would be to enable vertical scroll bar for all pages.
you can do this by going yo site properties.
File > Site Properties. (select vertical scroll as "Always") , please look at the screenshot for your help.

Clik here to view.
Hopefully this will make all the pages equally aligned.
Regards
Vivek
