Error Message :
When using Period objects, activated via a script, the object name of the Period object is passed to the column description in the activities window.
When the Period object contains a title, it is passed to the description column in the activity.
When choosing the option recurring when executing an object and selecting a Period object without a title, the object name is not passed to the description column in the activity window.
In summary, the behavior is different when using a Period object in a script than it is when choosing it for recurring objects.
Behavior should be consistent. If a title is present, it should be used regardless of how it was started.
