A process is able to create a new baseline revision without marking it current when no existing current revision is present.
Because of that, the baseline is not displaying some baseline information on tasks like 'Baseline Start' and 'Baseline Finish' attributes.
Expected Results: Tasks displaying all baseline information.
Actual: Task is not displaying all baseline information ex ('Baseline Start' and 'Baseline Finish').
Reported to Engineering: DE37439
Defect DE37439 Resolved in 15.4.
Workaround: Mark the baseline created by the process as "Current Revision" and this will correct the display.
