Problem with aircraft configuration


I have a 737-900 HGW (winglets) which had 17 units of cargo available for booking. I recently changed the routing that the plane serves and the plane now shows as having zero cargo capacity (ie there is no cargo available for booking). I don’t understand why. Any thoughts? As a result of the issue, I doubt using the plane will ever be profitable on the routes I am doing, as I’ll be missing out on ~$4000 per flight in cargo income.

Any help would be appreciated.



the route is too long for a 100% performance

or the other airports runway is too short for a 100% performance

Thank you
