Hi,
When you set up a new payment method (click on "new" in the payment list) you will see the complete list of the payment plugins you can configure.
In HikaShop 2.2.1, you can see columns for your published currencies and see if the plugin is compatible with the currency (or not).
Please check in that page if your payment plugins are right compatible with your two currencies.
