Pages created in the same way, and I try with the same content on some test pages -> no page look like another -> there a different gaps between top menu and top picture. (all are with default template and Overwrite the default page options OFF)
here are a small movie with the behavior : https://youtu.be/tEP-rY9Dl2o
Please go down the General Settings of each page and check out that the set up is the same. It looks from the video that some pages have an empty (but present) page header, while the others don’t. This creates distance between the menu bar and first image.
