Smart Resume - Atlanta CBS Station issues

For a while, none of my CBS recordings from our ATL station (WUPA) show the Smart Resume markers.  All the other major networks -- ABC, NBC, and FOX -- DO show Smart Resume and it works fine on those recordings.  I've been through all the Level 1 troubleshooting with Xfinity Support but I suspect the problem is not with my cable box but with the feed it receives from Comcast since Smart Resume DOES work, just not on my only CBS HD channel.

I suspect someone hasn't completed the backend switchover to the new CBS station (WUPA) but in any case, I would just like this resolved.  If you have any questions or need more info, please let me know.  Thanks!
