Cart subtotal rule not working correctly with multicurrency plugins

Hello,

I’ve a Woocommerce website in which i’m using Advanced free flat shipping plugin to setup shipping fees based on multiple criteria.

Though, the plugin doesn’t seems to work well when the active currency is different from the currency in which Cart subtotal rule value was defined.

I would like to know the best way to make this rule work with multiple currency.

Can you help me please ?

Thanks
