Questions about TFs project portal website task display

After a team project is created using TFS, a project portal is automatically created, which can automatically collect information from the team Foundation server and generate corresponding reports, such as the bug rate and project speed, problem list. There is a task connection, and it seems that the task of project development cannot be obtained directly from TFS (Note: there is a corresponding task or work item in vsts)

I don't know if the project portal does not have the function of directly reading tasks, or is there a problem with my settings? Hope you can advise me ......
