Moving footnote from one position in the tree to another

When I move a footnote node from one position in the document tree to another, the superscript identifier at the start of the footnote text is lost. Is there a way of getting this to reappear?

Thanks for your request. Could you please provide me code that you are using to move footnote? I tried to use the following code and all works fine.

Document doc = new Document(@"Test230\in.doc");
// Get collection of footnotes
NodeCollection notes = doc.GetChildNodes(NodeType.Footnote, true);
// Get first footnote in the collection
Node firstNote = notes[0];
// Move footnote to the end of document
// save document

Also please attach your document.
Best regards.
