How did you create the PDF document?
The PDF document was created in microsoft word, also the parts that have the green or red wavy underlines, are imported from Powerpoint.
Is there a way to remove these red and green lines without having to edit the powerpoint parts eg instead of going into power point making the changes and then bringing them into word again.
So if they could be removed from the word document alone.
You may use a forum for Microsoft Word.
