Payment Methods showing in email notification

We have a payment plugin os_offline_cash which we have renamed as BACS. We only use this payment method when putting bookings on from the back end. However despite choosing this payment option, the email notification to the customer simply says

EB_PAYMEMNT_METHOD Offline

Any ideas why and how to sort this?

I think it happens because the backend language file lack that language item. Could you please open the file administrator/language/en-GB/en-GB.com_eventbooking.ini, add this language item at the end of file and check it again?

EB_PAYMEMNT_METHOD="Payment Method"
