License Setup changes without user interaction and reverts to previous configuration

Issue

The configuration in "License Setup" changes autonomously meaning that you open "License Setup", make a change, close "License Setup", open "License Setup" and the configuration has reverted to what is was before the change was made. It reverts back to what it was before making the change.
