Netflow on GRE Tunnel Problem

Netflow on GRE Tunnel Problem

Are there any issues with Netflow running across a GRE Tunnel? I'm checking out various netflow products - trying out ManageEngine and on a Tunnel there is gap in the data.

Could someone explain what the problem could be here?

I have included a picture of it along with our router config - all the ips, etc.
