Clock setting?

2010 Disco 4.
This should be easy. I want to change the time display to am\pm from 24hr.
I go into the menu, pull up the clock change screen, change to am\pm and it works fine until I turn the car off. Turn on again and I'm back to 24hr.
Changing the time works fine, problem only with the time format.
Do I need to change the CCF?

I think you have to do this at the same time as setting a new time. Try changing time by a minute when you do it.

Good idea. I'll give that a go.
