Thanks for opening up a Support case.
And, in doing a bit more troubleshooting for you, I think I have partially reproduced your issue.
When Toad gives me the message that the job was created, I have to hit Refresh (Shift-F5, or View->Refresh All) in order for the new job/s to appear in the Object Explorer.
In one case, I actually had to disconnect/reconnect to see the new job, although users shouldn't have to disconnect. This all done in v 8.0.
