Why are certain activities in the Master Schedule not contributing to the overall progress bar of my projects?

Master Schedule Progress

If activities are added to the master schedule after an original baseline has been set, these activities will not contribute to the overall progress of the project. To address this issue, you can rectify by setting a new baseline in your master schedule. It is considered a best practice to create all activities in the master schedule before setting a baseline. Additionally, ensure that more detailed information is included in tasks under the lookahead for better tracking and monitoring of progress.
