Cannot change comment author
Hi, I have an issue with changing author name to comments. I have sent out a PDF document for review and received alot comments from a handfull of people. Each of them have returened with a separate pdf-file with thier comments. In two out of five PDFs I have been able to change the Author preference from their MS default name their actual names. But in three of the PDFs I cannot manage to change the name. I get the pop-up to open and fill in the Authour name, but the change does not follow through.
One thing I have noticed is a slight difference on the looks of the comment properties pop-up window on the ones that I can change author on compared to the ones where I cannot change the author name.
This is how it looks on the ones where I CAN change the comment Author name:
And below is how it looks on the PDFs where I CANNOT change comment Author:

Any clues?
Kind regards
