Choose currencies to show per country, Geolocation does not work

Hello, we need support in our website https://online.globalstd.com/checkout/
We have installed Multicurrency plugin, so we want to know if you can help with this:

We already added a few currencies with a specific countrys but apparently isnt working because always is showing all the currencies, ignoring the currency restriction by country.

We followed your setup guide and this parameters are not taking effect:
. Currency by Country: Work with Auto Detect turned on. Currencies will be displayed base on customers ‘s countries.
. Countries: Select which currency will be displayed for customers from which countries.

Thank you!
