Right number, wrong name

Starting today, when I call my home phone from my cell phone, my Caller ID at home is showing my cell number, but an entirely different name as the caller!  It should come up as "Wireless Caller" and show the number I'm calling from (my cell); instead it shows someone's first and last name, then my correct cell phone number.  Can someone advise me on what to do about this?  My cell service is not Comcast, but my home phone and my Caller ID service are Comcast.  "Wireless Caller" and my cell number have always come up on my home Caller ID, until today.

UPDATE: i tried a test, calling my second cell phone from my first cell phone, the one I was using today.  It comes up CORRECTLY on the second phone's Caller ID.  The problem seems to be with the Comcast Caller ID service.
