iStore Default/Preferred Addresses

iStore Imp and Admin Guide states that.... Preferred addresses -- Users can flag one billing and one shipping address as preferred. Oracle iStore then uses the preferred addresses when data is defaulted into shopping carts during checkout. Note that if a new address is created and marked as preferred, the previous preferred address is unmarked as preferred.

However, I have done the setup, logged a Ship and Bill address as the preferred, placed an order via iStore and the addresses do not default in.

I have applied a Shipping Method as also detailed, i have bounced the apache server and still I cannot get the addresses to default.
