  Manual Changes: If there were manual changes made to the task sequence or dependencies, it could lead to inconsistencies.
  
  Solution:
  
  Check Task Dependencies: Review the dependencies of the tasks involved. Ensure that the predecessor task is correctly defined and that the successor task is completed before the predecessor is executed.
  Adjust Task Sequence: Modify the execution sequence of the tasks to ensure that all dependencies are respected. This may involve re-scheduling tasks or changing their execution order.
