If this is an Automator Folder Action, then it will run once when a file is dropped on it, and any subsequent write (e.g. copy/rename/etc action on that file within that assigned folder will cause Automator to run the script repetitively.
If that is your scenario, you will need to revise the Folder Action script.
If not, then Automator does not reveal visually what Automator Service (Quick Action) or Workflow it is running. Typically, Automator applications are saved to your Desktop for direct access, and Services/Quick Actions are saved in your /Users/username/Library/Services folder. If the name of the Service is not a telltale of its intention, and you cannot spot the difference visually or by creation date, you will find yourself opening each of these Services with Automator to investigate its code.
