Can't get 'kiosk mode' to work on one page on my tablet, but I can on another?

I use Fully Kiosk browser on my tablet.
It shows two pages depending on the situation in the room, one page has the ‘kiosk mode’ working, the other one doesn’t, it sort of just ignores it.
It’s regular urls for the panels.
The kiosk settings are in the top of the panel configuration (added in text mode) and are identical.
