Issues with email sent after donation

The email that is sent after a donation (both the admin one and the donor one) has a few issues:

(1) I have disabled Recurring donations on the back end, yet even though the donation is then shown as it should be at the backend, the email shows Donation type Recurring

(2) The next line shows JD_DONATION_AMOUNT rather than the actual text (I checked in translations option and it's set up okay)

(3) For the payment option, again it's not showing the actual text but instead says JD_PAYMENT_OPTION

I have version 4.3
