Reader only displays half a vertical page

[JudyG46]

Suddenly documents I send to Adobe Reader DC only show half the document (vertically). If I increase or decrease the zoom or change the orientation, it is still only half a page.  This issue just started. Thanks for any help.

Can you explain the problem?  I can see all pages.
