Magento’s PayPal Standard Payment on a German store

Just installed fresh your Magento shop and you are trying to set-up the PayPal’s Standard Payment method?
If you already set the Merchant’s Country, you won’t be able to configure anything else BUT PayPal Express Checkout.
That is not a bug, that’s actually how the PayPal Module is configured.
The workaround is to first change the Merchant’s Country to any other country, configure PayPal’s Standard Payment and then change the country back to Germany.
( System -> Sales -> Payment Methods )
