The Project/Task progress bar shows up for all the projects/tasks except for one. The permission assigned to the user has the option enabled.

The Project/Task progress bar relies on two factors, first is the estimate and the second is the actual hours entered against that particular Project/Task. If the estimate is not setup for that Project/Task the progress cannot be calculated.
Edit the Project/Task and ensure that there are estimates defined for the same. To edit and provide the estimates for a Task, follow the steps below:
  • Login as administrator.
  • Click on Projects tab at the top.
  • Open the project on which Tasks/Sub-tasks need to be edited.
  • Click Edit under Project Structure.
  • Click the Edit icon for each of the Task and then provide the Estimates.
  • Click on Save.
