The problem occurs because Fallback shape has revisions while the DrawingML hasn't. As a workaround please use the following code:
Document doc = new Document(MyDir + @"nicoleflyer_removedMarkup.docx");
PdfSaveOptions opts = new PdfSaveOptions();
opts.DmlRenderingMode = DmlRenderingMode.DrawingML;
doc.Save(MyDir + @“15.7.0.pdf”, opts);
Please let us know if we can be of any further assistance.
