Hi together,
I'm using the menu dialog, not the context menu, for converting endnotes to footnotes. Scope: Document

The result is not as expected.

There are 7 endnotes in my document. Only 5 were detected by the conversion and only 3 of that 5 were actually converted. In one of the not detected endnotes the text has changed after the conversion. Some separator characters were added.

I am showing all this in more detail at the Adobe InDesign Forum and at InDesign Prerelease as well. Together with a link to my test documents.

Please see into:
