Bookmarks and Inserting Merge Fields

I think I found a bug. I have bookmarks around the mergefield. Then I run a Mailmerge. Then I want to take the merged document and find the bookmarks to insert mergefields again. I can’t seem to get it to work. Does anyone have code to do this?

Hello
Thanks for your request. Please try using the following code:

Document doc = new Document("C:\\Temp\\in.docx");
doc.MailMerge.Execute(new string[] { "Test" }, new string[] { "Value" });
// Save output document.
doc.Save("C:\\Temp\\out.docx");
Document doc2 = new Document("C:\\Temp\\out.docx");
DocumentBuilder builder = new DocumentBuilder(doc2);
builder.MoveToBookmark("MyBookmark");
// Insert MergeField
builder.InsertField("MERGEFIELD Test2");
// Save output document.
doc2.Save("C:\\Temp\\out2.docx");

Please see the attached documents.
Best regards,
