How come my SMS messages won't show up in my SMS inbox on my Blackberry Bold

[Nyki]

9700 with OS 5? I realized that on my Blackberry Bold 9700, when I get a SMS message, it only shows one person and the messages they sent. If someone else texts me, the texts come under the first person's name, and it only changes when I delete the entire inbox (which is the one person). Can you tell me how to get all my texts correct in my inbox?
