Missing Endnote Reference Numbers after Placing
I'm importing text from a word document into InDesign, and the word doc already has endnotes, links, and superscript endnote numbers. The problem is when I File>Place the text into InDesign, everything shows up except for the superscripted endnote reference numbers. The crazy thing is if I right-click on an endnote, and click "Go to endnote reference", InDesign will navigate to the correct page, but I get the warning below.

Nothing is locked nor hidden. And if it is, I don't know how to find it. Can anyone tell me why the reference numbers aren't showing up and how to fix it?
