In Flight Reputation problem

So in S4E, I'm flying 767s with business and economy class on medium range, high demand routes. I decided to experiment with adding the Concorde with just first class on those routes. When I add the Concorde, the In-Flight Service bar for first class is significantly lower than the in flight service for the other classes. If I remove all flights, and then add the Concorde first, and then add back in the 767s, It's the business and economy class In-Flight Service that is super low. The thing is, I have the exact same In Flight Service for all three classes.

This also happened when I tried adding A330 flights to a route that I was flying with 767s. The First class In-Flight Service was unusually low even though they were the exact same as the other classes. 

In Flight Service levels changing just because of the order of when the planes were added? That doesn't seem right...
