TF234031: One or more work items that were imported to the project plan are missing data because a list separator value appears in the following field: {0}.

To ensure that all data for the work item is included in the project plan, contact the administrator to remove any list separator value ({1}) from the values of the reference field in the team project. Then, refresh your project plan to include the missing values.
