Why is word inserting dots into output of RTF file

Why is word inserting dots into output of RTF file

I am replacing text in RTF documents for a mail merge and have come across
a problem with Microsoft Word 2010, I assume the same is occuring in
earlier versions of Word. The problem is Word is duplicating paragraphs
and inserting "..." at the start of the paragraph.
I would like to know why this is happening? Seaching the raw text does not
find a string with three dots. I assume there is an error in the
formatting or structure of the text?
Note that opening the same document in Libre Office or Open office does
not have the dots or duplicated paragraphs.
