Combining PDF Files Into One

I'm creating a 2 page PDF document using two separate PDF documents.

MergeDocument document = new MergeDocument();
PdfDocument pdfdoc = new PdfDocument(@"Page1.pdf");
document.Append(pdfdoc);

ImportedPage 2ndPDFPage = new ImportedPage(@"Page2.pdf", 1);
document.Pages.Add(2ndPDFPage);
document.Draw(@"FinalPDF.pdf");


Some of the fields in both pages have the same field name. The final PDF document renames the duplicate fields in the 2nd page to include
a parentheses(2). So for example,

Page 1  has field named      description
Page 2  (which has a field named "description" also ) will result in a field being  renamed  description(2)
in the final PDF file.

Is there a way to prevent that other then making sure there are no similar field names in both Pages?

According to Microsoft Copilot....

"It looks like ceTe.DynamicPDF automatically renames duplicate field names when merging documents. Unfortunately, there isn't a built-in way to prevent this behavior other than ensuring unique field names across pages."
