The earliest recollection of this bug is traced back to PAN-OS 11.0.0 - July 22, 2025. This bug is fixed in PAN-OS versions 11.0.4. Fixed an issue on Panorama where, after selecting managed firewalls and creating a new tag, the managed firewalls were automatically unselected and any new tag that was created was applied to the managed firewalls for which you initially created the tag. On the Panorama management server, after selecting managed firewalls and creating a new Tag ( Panorama Managed Devices Summary ) the managed firewalls are automatically unselected and any new tag created is applied to the managed firewalls for which you initially created the new tag. Workaround: Select and then unselect the managed firewalls for which you created a new tag.
