I reset mine this morning and they all came back. I used the reset button in the Gateway under troubleshooting. There is another thread here where a Comcast support guy said you might have to factory reset the device to get them back. Luckily I did not have too.
Your software is newer than mine. My modem was just replaced yesterday though.
