I lost lower channels on my Roku 3

I have two Roku 3 devices.  Normally I am able to watch the lower broadcast channels such as NBC, ABC, Fox (Channel 2, 4, 5, 7, 9, 11 etc).   All of a sudden my channels now start on channel 33 instead of channel 2.  

They disappeared on both devices.  I tried rebooting the roku, rebooting my cable box and cable modem.  Even tried a reset of one of the devices and I can't get the channels.

I know there is a filter and it's not that.  Anyone else having this problems?  It just started a few days ago
