The values between these two screens are inconsistent. The panel that appears when you click on the truck station image tells us that the production cost of a level 1 truck station is 1000 workers, yet it costs 1100. Likewise, it says a level 2 truck station has a production cost of 3400 workers, yet it costs 3700.
I'm seeing this happen with ALL types of buildings.
As an added balance suggestion, it's odd that upgrading a truck/rail station makes it less manpower efficient. If anything, it should be more efficient.
