Editing this post for clarification:
The Google Maps setting in the JobRoller admin does not relate to the actual default search location, it is just a setting for the actual Google Maps language for your site.
I have discussed this further with our development team and have been advised that once you enter a location into the search, the actual search results are completely reliant on Google Maps, and JobRoller does not have control over this aspect of the search. So, if you specifically want the US location "Vancouver" then you need to type "Vancouver, US", or even "Washington".
