Netflow Analyzer seems to double count my ESP/GRE traffic

Netflow Analyzer seems to double count my ESP/GRE traffic

 Any thoughts?

 

I get double the true traffic when Netflow analyzer counts the IPSEC/GRE packets. It breaks them down into 2 seperate categories yet counts the same packets twice(one for each protocol) essentially doubling the amount of traffic across the interface.

 

it shows as:

 

ESP_APP----- 45%

GRE_APP-----43%

 

and the packet source and Destination are exactly the same; and the same percentage breakdown inside the protocol readouts.

 

?????? help
