Confusion Created to the Invoice Receiver because of the phrase - "Payment Method: OFFLINE_PAYMENT"

Dear FluentCart Team

In my site, some customer just paid some amount for a product he purchased using the QR Code placed on my site (Direct Bank Transfer Payment mode).

Actually, he did online payment for the product through mobile banking. But the email invoice showed -"Payment Method: OFFLINE_PAYMENT". I think it can be rephrased differently, for example "Payment Method: MANUAL_PAYMENT". This phrase then would include all such payments as CoD/Direct Bank Transfer/QR Code.

Thank You.
