As you can see from the images Kodi's guide doesn't always reflect the same data as DVBLink's via a browser (in this case iZombie). I tried a couple of different Kodi clients (Windows and OpenELEC) and rebooted them a couple of times. The images were taken within a minute of each other. Is there any way to refresh Kodi's schedule data?
I believe everyone is running on the latest version. If it helps the two channels swapped affiliations last January (CW and CBS).
