Summary:
A user with permission to see all projects may not able to see some or all projects in the list, because the filter Display in the List Projects page may be set to My Projects. This displays only the users projects and not all available projects. A Web TimeSheet Administrator who is not part of any project will not be able to see any of the projects unless the Display filter is changed to All Projects.

Note:
The second filter helps in displaying the Open, Closed or projects with both the status.
