Workflows are starting multiple times for each list item created or modified depending on the configuration of the workflow.
More than one version of the workflow is configured to 'Allow' on the affected list:
- Navigate to the list and click 'Workflow Settings'.
- Click Remove, Block, or Restore a Workflow.
- Mark each workflow to 'No New Instances' other than the current version (or click Remove, if they are no longer needed).
