Graph labels for "Seat-km" and "Passanger km" both show as "pass. km." on graph

[kylofon]

Where: Line management and Convoy screen, in the "Graph" subtab

What: When choosing to display the graph lines for "Seat-km", the line is labeled as "pass. km."

Expected: When choosing to display the graph lines for "Seat-km", the line is labeled as "seat. km."

Solution: I'm told this is related to the localization, which is missing the "Seat-km" string for all languages except JP.
