OMP 3.1.2 - Chapter PDF will not display

Hi,
Version 3.2.0.0 or version 3.2.0.1 does not show chapter PDFs correctly. I noticed that if we add files to chapters, after adding the second one, the file at the first chapter is deleted.
The order I follow

  1. Uploading files to Book manuscript + 3 chapters in Production Ready Files (type Chapter Manuscript)
  2. Addition 3 chapters in Publications / Chapters
  3. Adding 4 entries in Publication formats (one for main text and 3 for chapters) and uploading files to each of them
    Alternatively in item 3
    Adding one entry in Publication formats and uploading 3 files

Files PDF in chapters do not appear correctly,
Peter
