  Clear the Working Panel: If the error is due to stale data, try clearing the working panel or refreshing the session. This can often resolve issues related to state inconsistencies.
  
  
  Debugging: If you have access to the development environment, use debugging tools to trace the execution flow and identify where the duplicate addition is occurring.
