Blank Pages After Combining PDFs

[kendalgoodrich]

I have some PDF documents I am attempting to merge. If I only merge single page pdfs, they merge and display correctly. If I attempt to merge multipage PDFs, only the first page of each document show up in the merged file. All other pages show up as blank pages. And when opening with Acrobat Reader DC, I get a message stating:

An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem.

I have downloaded the latest Spire.PDF 5.11.2 and am having this issue.

Thanks,
Kendal

And FYI, I tested with an alternative component(ABCpdf).
It was able to successfully merge the pdf documents without any issues.

When testing with the Spire component, I read a single 2 page pdf document into the PDFDocument. I then immediately saved the file out to another pdf. When opening the new document with Adobe, I received the same message. Although the 2nd page was visible.

It also does not appear to do this with ALL pdf documents.

Here is a sample of the code which I used to duplicate the issue.

string[] files = new string[] { @"D:\History and Physical-03072006-1715-1.pdf", @"D:\History and Physical-03072006-1719-2.pdf" };
PdfDocumentBase doc = PdfDocument.MergeFiles(files);
doc.Save(outputFile, FileFormat.PDF);

I am attaching the referenced files.
The data within the files is sample data and not actual data.

Thank you for your prompt response. Any idea on the usual time-frame for bug-fixes like this. Reason I am asking is that I have a time-sensitive project that I am using this library on. If the fix time-frame is too far out, I may have to resort to another library.

Thanks again,
Kendal
