Activation issue with 2checkout and foreign currency

We are experiencing a new problem where subscriptions are not activating (they are no-status) after purchasing our recurring subscription plan (SONATA) in a foreign currency. If purchased in US dollars, everything is fine. If it is a fixed 1 or 2 year subscription, everything is fine.

Also, sometimes the purchase amount is not correct when we convert the foreign currency amount back to US dollars. People are being overcharged.

We are not sure if it is a problem with 2checkout or PayPlans. Thank you for your help!
