On of my jobs was inexplicably set to 'restore only', and hasn't been running for a month, so I wanted to delete it and create the same job afresh.
Deleting the job worked fine, and the name disappeared from the 'All jobs' list.
When I try to create a new job, select '1/Manually choose which files'', hit Next
go through selectiing the destination (option 3

In the Job Setup screen, when I enter the new Backup job name to be the same as th eone I previously deleted, the field is highlighted red and a warning appears about the 'Backup Job already exists' and the Next button is disabled.
This keeps happening even across a shutdown and restart of AISBackup.
Where is it keeping residual memory of the deleted backup job?
