Not sure why would you want to set those values, either in CMS settings or on the display themselves to 0, and not set it to something meaningful.
That being said, I’m not sure why would that affect google traffic widget, since you’re not using Display Location in it, you’re proving the coordinates instead.
Although I can confirm that it does indeed affect it - both player and the preview in CMS, which seems like a bug to me - we will look into it.
For now, you can either set the correct default values there or if you remove the 0 and save&refresh it should set the default values that are set during installation.
