Call waiting call accepted but no caller history in log?

[Thresher]

I seem to be doing something wrong...I accepted a phone call today while on another call and the cID came up but after the call I can't find the caller ID in my hisotry.

I feel like I have swiped and looked but it doesn't seem to be there. Is this already listed as a problem or an issue? Am I dong something wrong?

I did some basic searches but always came back to evo4g issues or older phones not wp7...

The call did show up in my AT&T billing online as a CALL WAIT so I seem to be stumped.
