Workflow not triggering on request

Hi , 

I created a workflow that is supposed to run on a sc_req_item but it doesn't look like its getting triggered correctly.  I've attached a copy of my workflow , there aren't any errors when I validate it and it is linked correctly to the servicenow request. 

I've also noticed that when I try to view the workflow context it says there is no records found and the status for the request approval is stuck at "Not Yet Requested". 

Thanks !!
