Duplicated pages, and now the fields auto populate on all pages

I have a PDF file where I duplicated a page multiple times to be used to each day of the week. But when I fill out the date, for example, on the first sheet, it is auto-filled with the same date on all the pages I duplicated. When I edit the second page to tomorrow date, it gets edited on all the pages. How can I prevent the form from doing this so I can input different info on each of these pages?
