K3 Not keeping settings?

Hi all. My K3 and K3 II have started doing some weird and funky things, like changing ISO and f stop without being touched by me, and also, to use an example, I set ISO to match EV steps, so function 2 in custom settings, and it reverts back to 1 after every time it goes into standby.
Anyone else experienced this, or have an idea why? Cheers.

Are you using it in one of the three custom settings? Custom settings have to be purposefully saved in the menu system otherwise they will revert back to the saved ones when the camera is switched off.

There is also a setting somewhere in which the user selects which settings are saved and which ones aren't.

No, not in custom, in Aperture Priority. Does seem odd! I'll look at the settings.

If you haven't used it for a while, you may have forgotten some custom settings. If all else fails try a factory reset and start your favourite settings over again.
