Removing White Space Between Pages

[riversurf58]

Too often, my existing documents open with white space between pages, even though I created them without any white space. Going through File>Options>Display and unchecking "Show White Space Between Pages" has no effect. And I don't know why it often reverts to being selected.

Is there another way to get rid of this white space? Sometimes it goes away on its own, but that's completely unpredictable. Help appreciated.

(Using Office Professional Plus 2016, Windows 10, but this problem has plagued me for years on every platform I've used)

Thanks
