See attached original and output files [Table and Charts 1.odt, Tables and Chart 1.pdf, Tables and Charts 2.ppt, Tables and Charts 2.pdf]
  2. PDF/A 1b conformance verification process is failing. this produce in all components (WORD, SLIDES, CELLS). See attached images [PDF-A-1b-1.png, PDF-A-1b-2.png]

MemoryStream stream = new MemoryStream();
wrkBook.Save(stream, pdfSaveOptions);
OutputFileBytes = stream.ToArray();
