Responsys Custom App blocked for waiting enactments

Hi,

I have a problem with a simple program (following screen) composed by a custom app on Responsys. The program is composed by a scheduler + my custom app + timer + end . 

The first step (the scheduler) is passed without problems, but it is when it should switch from my app (2nd step) to the timer (3rd step) that the flow stops, 

pointing out that there are waiting enactments. 

I also tried using a request for exit but it says "title": "Program is in published state or has never been published",

  "errorCode": "PROGRAM_IN_INVALID_STATE",

  "detail": "exitProgramEnactments - MyApp should be unpublished before terminating".
