Endnotes in book format continue off of page

hello, i am working on a book (currently in dissertation form) that has endnotes at the end of the entire book. right now, the endnotes are auto-populating on the very last page of the document. after i made enough endnotes to fill up that page, rather than stopping at the end of the page and starting a new endnote page, the footnotes are bleeding off of the page into the blank in-between space. i'd like for the endnotes to fill up multiple, continuous pages. i have tried a few things that have not worked, like copying some over to a new page, or attempting to figure out how to add a second endnote text box on the next page. thank you!
