Templates - Not able to use, treated as an incoming message

I have some template messages in templates folder. K9 sees the folder, I can get to the messages but they appear as incoming messages so the only option is to reply, but the reply is only to me as the sender and not any other recipients (who are invariably BCC’s.)

When viewing the message select Send… from the menu, then Edit as new message.

Many thanks… not the most intuitive but workable…S
