The earliest recollection of this bug is traced back to PAN-OS 10.1.9 - July 22, 2025. This bug is fixed in PAN-OS versions 10.2.4, 11.0.1, 10.1.9. Fixed an issue where the Policy filter and Policy optimizer filter were required to have the exact same syntax, including nested conditions with rules that contained more than one tag when filtering via the neq operator.
