Is anyone else getting simply wrong information?

I put in my work address and a time of one hour. It shows two of my previous home address as being over an hour away. It takes me about 40 - 50 minutes to get to work now from my current address. It took my about an hour from the other address.

Also, there needs to be a way to clear the map. Right now, I'm just overlaying times. I don't know if I'm just missing it on the UI but there needs to be a way to distinguish between adding more areas and replacing an area.
