RTOS/TMS320C6748: Can't see task/semaphore in Execution Graph

Part Number:TMS320C6748

Tool/software:TI-RTOS

I follow the <Intro to the TI-RTOS Kernel Workshop Lab Manual>, and do  the LAB8, which use task and semaphore.

But I succesuffly run the LAB, the led toggles right and I can see the task and semaphore in the ROV.

But in the Execution Graph, there  is no task or semaphore. How to show them?
