Can footnote popup be edited?

Hello,
An epub I am formatting has both footnotes and endnotes. When I am in Kindle Previewer and I click the footnote reference the popup header says "Footnote" and the footer says "Go to footnotes" a separate page where all the footnotes live.

But the endnote popup also says "Footnote" and "Go to footnotes" though it correctly goes to the endnote page.

Is there anyway to edit this?

Thanks,
Tom
