@Bob_Bent, Yes. I was following the Algosec guide. In page 70, it asked to select Permissions Profile. if there is no existing permission profile, we can create a new permission profile by click on New. In the Permissions Profile Properties dialog, enter a name for your new profile and select the required permissions.
I created this OPSEC application under Global Domain. Once application created, I did published. While doing the Reassign on Domain, that's where I saw the error where the permission object name was used before. That's where I wanted to modified the permission profile name but unable to find it.
