I think I have finally figured out how to keep the voice mail notification from remaining after checking my messages. I noticed the other day that it hadn't been happening but wasn't sure what was different. Then I remembered that I had been ending my voice mail calls by pressing # instead of END. Today, I absentmindedly pressed END instead, and the notification remained. I called and left myself another voice mail, called to erase it and ended the call with # and the notification went away. I don't know whether this is a US Cellular problem or a Genesis problem, but this small change fixed the problem for me.
