Bounce Rate metric not populated when using custom dimension as a secondary dimension
I had implemented the "Reader-Scanner" as custom dimensions (as suggested in Justin Cutroni blog here http://cutroni.com/blog/2012/02/21/advanced-content-tracking-with-google-analytics-part-1/)
While I am able to see this report separately under "Behavior" >> "Events". But when I want to add "Custom Dimension" of Reader Type as a secondary dimension under my "Acquisition" or "Behavior" reports - the Bounce Rate metric is getting set to zero.
Without secondary dimension the Bounce Rate metric is getting populated. Can someone please explain? Many TIA.
