On a few projects, the 'Actual end date' is showing as blank.
Steps to reproduce:
- Open the affected project, see Actual end date is blank
- View project tasks under Project Schedule related list tabs for that project, see Actual end date exists for all project tasks
Release or Environment
Madrid / New York
This will occur if there was an error while saving any child's task.
Try clearing the Actual end date of any project task > Save and then change the Actual end date back to the same actual end date > save.
