SCHEDULE BACK UP Operation Failed! get() returned more than one NormalBackupJobs

Operation Failed!
get() returned more than one NormalBackupJobs – it returned 3!

Re-create the problem:
Select Destination: anyone
Select Job: anyone, and delete it

Then add new schedule
Select Destination: anyone
Select Job: anyone
problem occurred:

Operation Failed!
get() returned more than one NormalBackupJobs – it returned 3!

The delete button disappears, and no way to delete jobs, the dropdown menu shows many jobs there, fail to pick and fail to delete.

Got the same issue, any fix?

I got the same error, just delete Backup Destinations and add it again. then “Schedule Backup”.
