The earliest recollection of this bug is traced back to PAN-OS 9.1.1 - July 29, 2024. This bug is fixed in PAN-OS versions 9.1.5. Fixed an issue where, when defining the match criteria for dynamic address groups on Panorama, the boolean AND/OR operators did not function properly. ( Panorama plugins ) When you use the AND/OR boolean operators to define the match criteria for Dynamic Address Groups on Panorama, the boolean operators do not function properly. The member IP addresses are not included in the address group as expected.
