Video changes to 50hz after initially going to 25hz

    So minor little issue.

    I have set the resolution on my wetek play 2 to 1080p 50hz given that most TV channels are broadcast at 50hz, saves changing resolution.

    However some movie channels are at 24hz or 25hz and normally that would change to the correct resolution. I can see in the properties that the frame rate is 25hz, so why does the system "think" it's 50 Hz after changing it to 25hz initially.

    Channel is 25hz kodi changes it to 25hz then to 50hz 5 seconds later. It has once or twice changed back to 25hz mid program only to change back again to 50hz 1080p
