Xfinity program guide for COMET channel

In May 2024 the Comet network for zip code 77590 (near Houston TX) was moved from channel 317 to 310.  Although we can access Comet programs, the Xfinity channel guide does not show the correct program listings for ch 310.  For example, at noon CDT it should display "Stargate SG-1", but it shows "Decked Out".  The station name is shown as KHOU4 but the programs appear to be for another network. 

I have performed a power-off/on reboot and a hard reset.  The problem persists.  Other cable boxes in this area (along with both my DTAs) have the same problem.  Please update the program guide for channel 310 with Comet programs.  (FYI: I notified the Comet channel over a month ago but have not received a response).
