That's happens if you're playing offline. The double fame bonus can only be triggered by going online. But once triggered, you can race offline as long as you don't turn your screen off. Else, you'll get that annoying time and date error which also cancel the double fame bonus.

You can still pause your game while farming, but make sure the screen is always on.

Or, just play online.
