Multi Currency doesn’t work

I’ve recently integrated multi currency system into our client store. Previously we only had Pound sterling and added Euro recently. It works fine when someone pay in Pound but when someone pay in Euro, payment received in USD with same amount as Euro into Worldpay admin account.
I contacted worldpay support and they said we need to choose ‘Settlement Currency’ as Euro when paying in Euro but into your plugin there is no option to add multiple ‘Settlement Currency’.

Please suggest.

Thanks in advance.
