Hi piper27. I don't have your phone but I do have a HTC. I can't find any specific settings to adjust what the caller ID displays. If it was working and now is not... I might suggest doing a battery pull. Once reinserted, the phone will go through a hard reboot which sometime clears wonky things HTC phones will do from time to time. I hope this helps.
