WooCommerce Free Shipping Bar + WooCommerce Multi Currency

Hi,

I have purchased both the plugins above.

However, I am having a big issue:

-Currently we ship to US and Singapore.
-Shipping fee is USD20 to US and Free Shipping for orders above USD100.
-Shipping fee is SGD5 to Singapore and Free Shipping for orders above SGD50.

How do we make the Free Shipping Bar reflect the above base on the currency visitor choose?
eg. If customer choose USD, it should show FREE shipping above USD100.
eg. If customer choose SGD, it should show FREE shipping above SGD50.

I bought WooCommerce Free Shipping Bar plugin for this purpose only. I will be disappointed if this cannot be achieved as both plugins are coming from Villa Theme.

Kindly Assist
