Taskflow Phantom Runs - cannot find why

Hi,

Recently, our client discovered that there were some Taskflow executions at Midnight in Production that were not scheduled.

We shall check when this started, apparently the last three or four days, but it seems that some kind of "phantom" executions existed already in Preprod environment.

We searched in Taskflow for ETL-016 (affected by this schedule) that runs at Midnight and found nothing in its schedule.

We checked also in ODI because there is a batch for ETL-016 that runs later (at  01:30 approx).

No connection in any other environment is pointing to the Production.

Taskflow schedule:

Example of the phantom run on Nov 5th at Midnight.
