Comment summary creates duplicate pages

I'm trying to create a comment summary from a PDF with the following settings:

The PDF in question was printed from a .docx. When I create the summary, everything looks great until the sixth page of the comment summary. For the next 15 pages to the end of the summary document, all the pages look like this:

The PDF page is displayed in duplicate in the summary. The duplicate page image runs into the comments column, and the duplicate comments wrap around and run into the first page image. I got this result with three different PDF documents.

I have tried the following:

1. Export data file, reprint original PDF, import data file.

2. Turn off track changes in original Word file, accept all changes, set markup to no markup, print new PDF, import data file (see 1).

Neither of these produced different results.

Has anyone ever seen anything like this before?
