The earliest recollection of this bug is traced back to PAN-OS 9.1.10 - July 29, 2024. This bug is fixed in PAN-OS versions 9.1.10. Fixed an issue where, when using the CLI or API, configurations for policy rule services or applications that either used custom settings and default settings together, or used multiple default settings together, successfully commit instead of failing or displaying a warning. Note To use this fix, you must delete previous application or service settings in the configuration.
