Hi,
I got a similar issue. In my case the approval permission wasn´t right.
If the approval was sent before the correct permission was set in the policy the job will stuck.
The only way to remove this stucked jobs is to clean it out of the database.
In my case, VMware engineering is working on that.
I will suggest to open a SR.
