Top 5 applications, data is not available.

configured Sflow on nexus 9k. Version is 7.0(3)I7(6)

sflow collector-ip vrf default

slow collector-port 2055

sflow agent-ip

I am able to see node along with interfaces and the port number for the solar-winds server is correct.

I am unable to see any data for the top 5 applications graph along with the top 5 conversations graph.

This is the same configuration on my other nexus 9k and that node is showing data on both graphs correctly.
