I am adding an endnote to a document. There are no footnotes or endnotes in this document so far. Yet, when I add an endnote on the Reference tab, it is given the number '2'. That doesn't make any sense to me. I clicked on "Show notes" and don't see anything besides the '2' on the "Notes" page I created at the end of the document. Why in the world is it showing '2'? I tried clicking on the reference in the text, but saw no way to change the number. How can I fix this, please? Thanks.

I am using Office 2019 on Windows 10.
