Looking for issue about CEC with my Sony TV I may have something similar. I’m on the October update and after a while the CEC entry disappear from the external source. On Sony TV you can select external source but when an CEC device is connected and recognized it appears on the top of the external source list. After stop/start both TV and RPI the entry appears but after some time (days? to determine) it’s gone. HDMI cable changed already, CEC adapter enabled/disabled, no change.
I added a new HDMI device on the setup but by Sony only one HDMI is CEC enabled. I’ll update to the last version and see if it helps.
If it helps… (not updated yet)
