Created attachment 185360 [details] fdo53985.docx from ooxmlexport8 Each time the document is saved, an extra, empty paragraph is added at the end of the section. These sections have a block table (a table directly in the w:body, not inside of a w:p paragraph) at the start of the section, and so a dummy paragraph is created. The dummy paragraph was preventing bRemove from becoming true when reaching the end of the section containing a sectPr. Steps to reproduce: -open the file and notice there is only one empty paragraph under each table. -save as DOCX and reload. Now there are two empty paragraphs. -this increases by one on every save.
