start_location not working

I have stores located in different states within Australia.

I have set up state specific pages and I only want to show stores from those states.

To achieve this I am using ‘Categories’ within the following shortcode:

[wpsl template=”default” category=”QLD” start_location=”brisbane, australia”]

This is loading the stores correctly, however the issue I have is the start_location is always ignored.

I have tried setting this to Sydney NSW or leaving it blank, and it seems the start_location simply being ignored? What could the problem be?
