Hi BobSovers-5969,
Welcome to Microsoft Q&A.
If a schedule has been created in the job, the unique identifier for the schedule and the content of the schedule will be automatically included when generating the script. And we have to remove the script about msdb.dbo.sp_add_jobschedule, otherwise, the schedule will still exist in the new job generated by the generated script, even if we delete schedule_uid.
If this issue bothers you, I recommend you submit it to the Microsoft feedback at this link https://feedback.azure.com/forums/908035-sql-server. Your feedback is valuable for Microsoft to improve the level of products and service. Appreciate for your understanding.
Best Regards,
Amelia
