Endnotes Come Out As Letters

I searched for this topic but didn’t find any discussion on it, though I presume it must be a common issue.

After compiling to .doc or .rtf my endnotes appear as superscripted i or ii instead of 1 or 2. This is within the text and in the endnotes. Doesn’t seem to be a problem when Export to RTF is set to “Footnotes” only “Endnotes.”

How do I get endnotes showing as numbers?
