BB Torch :: Message Shows A Green Bubble Like A Draft?

I sent a text to my friend. They replied but it came as a seperate thread not as a reply to the one I had just sent. Usually I can scroll up and read all our texts in seperate boxes. I have the bb torch 9800. This is what I see: from the main screen click on test messages. It shows as a green bubble as if it is a draft message and 4 characters that I don't ever remember typing. But when I click on the message all I see is their reply message to me but can't see the 4 characters from the supposedly draft message that shows in the list of text messages. Also there is no box at the bottom to type my reply. If I go back to the list of text messages and click the bb button I can click reply but when I do once again all I see is their message but still no 4 characters of the draft message or text box for me to type in.
