I am using ( Quattro Pro x8 and Windows 10. When I tried to save my most recent spreadsheet (only has 35 rows; so 1 sheet), it saved. But when I opened it in Adobe Reader CD Version 19, the spreadsheet sheet actually twice (repeated the entire sheet or 35 rows twice, like a page 1 & 2 of same thing). Why? What happened? Never done this before. Any help appreciated.
