Able to see context data in Bloodhound but not able to see the same in Sitecatalyst/Discover

Hi All,

I am able to see all the context data on the attached page in sitecatalyst/discover other than sourceofvisit .

Can you please tell me a possible reason for this .I have mapped the context  data  sourceof visit correctly to an Evar ,but not able 

to see its value in sitecatalyst.

Thanks & Regards,

Anand
