Breadcrumbs Point to Page with Bizarre Map Centers

Hi there,
I’ve got multi location installed and configured for multi locations at country, region and city. When I navigate to any specific detailed listing such as http://cabinrentalsonly.com/listing/canada/british-columbia/fraser-valley-a/blue-lake-resort/ and then click on the breadcrumbs link for British Columbia, the map that displays is centered and zoomed at a location and level that makes no sense. Furthermore, if I manually zoom out to that I can see the whole province, then I can only see 3 or 4 listings when there are really more than 90 listings in the province. The expected behavior is to be centered such that all of British Columbia should display and all of the listings markers or clusters should display. Help!
Thanks in advance, Wayne
