MarketPress UPS wont calculate with Hong Kong origin

Just switched from Marketpress Pro and WP 3.9.1

Selected UPS for the shipping calculator, with Hong Kong as the base country, and regardless which variables I choose for the UPS calculator i always get the error

"This measurement system is not valid for the selected country."

Changed the base country to Canada, and it works beautifully!

here's a previous thread with the same issues unsolved.
