Adobe Acrobat Dynamic Stamp information

We have 5 licenses for Adobe Acrobat 2020 - 1 license key for 5 users

All installations of Acrobat appear to share the same Identity information so when they go to use Dynamic Stamps, it give the wrong name for the user.

How can I modify this so that each user shows their own information?  Modifying the information in the Identity area modifies it for everyone
