No insert space mark or insert paragraph mark after caret when commenting
When I use the insert text commenting on Adobe Acrobat, sometimes I need to say to insert a space or insert a paragraph break. All of the documentation says that if I insert a space I should get a ^_ symbol. And if I insert a paragraph, I should get a ^ paragraph mark.
That doesn't happen for me. All I get is a ^. This is confusing for the other users since the comment attached only has a space in it, and it isn't obvious what I want. And there's no way to be clear about the insert paragraph. Here's a picture of what I get:

Here's what a coauthor gets when he does the same thing:

I've looked on all the adobe help sites and there's nothing to say why my installation is behaving this way. I've checked for updates, and it is updated. I've tried reverting to old acrobat. That doesn't help. I went back to new acrobat, that didn't help. So anyone have any idea what gives here?
