Dynamic Stamp Reviewer Name Changes upon Comment Download from Shared Review

Question

When reviewers publish their dynamic stamp to an active Shared Review and I join the review, it downloads their comments (including the dynamic stamp) but when it downloads to my copy, the name on the stamp changes from their profile name to my profile name. If I double-click on the stamp, the reviewer's name shows up on the comment pop-up yet my profile name remains on the stamp image.
I've dug around in the forum and have found no information about this problem. Does anyone out there have a fix for this or have you seen this problem as well?
It happens whether the review is initiated and stored in a network server directory, or using a SharePoint workspace.
No matter who has initiated the review, the renamed stamp appears in other participants' review copies. This was not happening at all before (we have been using Shared Review since 2012).
It just started happening and it is occurring to others at our company as well. Initiating from different versions of Acrobat (ranging from Acrobat 9 to Acrobat 10) results in the same problem.
Some reviewers' names are showing correctly and some are replaced with the user's name. See below.
Below you can see the first approved stamp name (and time stamp) is different than the pop-up.
The second is the same as the reviewer.

Answer 1

I don't have the answer but I've seen the same thing, only with it twist. It seems to be related to the disappearing comments that others are talking about.
We use the dynamic stamps just as you do and for certain users, the stamps disappear when the review file is opened again, no matter who opens it. You can see then listed as having added comments as the file is opening but no stamps are showing, and they aren't listed in the comments window once the file is open.
But we have one user who DOES see the stamps - except that they have his name instead of the user that actually stamped it! So for some users, there's no problem - they stamp the file and everyone sees it fine. For others, the stamp disappears whenever anyone except that one user opens it, and he sees his own name on them. We all use Acrobat X except this one user, who's still on Acrobat 9.
This all started recently and the number of affected users seems to be increasing. I firmly believe that it's related to recent updates that have been sent out, though I can't prove it. Not sure why else the problem would just start happening, and not to every user.
This is a serious problem that needs to be fixed!
