Process Route Cannot Execute

Hi，

We want to use Process Route with PLMWUI. I have activated  WS00100012 and TS00100010 and all the other required configuration in PLMWUI.

When I start a workflow on Process Route, the agent received the work, when executing this work item it doesn't lead to the activity but the Process route item(as pic below). What do i missing in the configuration?

Regards
