City Statistics - timeline changed -how to get back?

[GMOEU]

In 'City Statistics' (in the same panel as Save Game, Options etc.) the timeline used to be the time (year/month) of the game.
But somehow the timeline has gone to the real current year.

I don't know how that happened.

How do I get it back to the year/month of the game, not the real year?

Thank you

This is what I see:

Looks like the statistics timeline has reset for you. This is probably caused by one of the mods you're using.

Probably Rush Hour, it tends to break the statistics window :/
