sticky connection on bandwith balancing no traffic flow

I have deployed bandwith balancing in my ROS based on Tomas Kirnak’s presentation at MUM New Orleans 2015.
Works fine on failover.
Issue is I dont see any traffic flow through the sticky connections so I assume they don’‘t stick. Should they ?
I have run the script over a dozen times but can’'t find any config errors.
Also the automating on basis of bandwith usage doesn’t come into effect. I’ve played around with the treshold but no joy.
So basically 2 interesting issues.

I have attached a screenshot of the mangle rules with the traffic flows as also my complete config.
Anyone any clues?
