[K-S2] ISO no lower than 200 in Auto ISO (100-x)

Has anyone else experienced this behaviour? I don't remember exactly, but I think this happens in all modes (Av/T/TAv) when I have Auto ISO enabled with a range from 100 to whatever.. Doesn't matter how much light there is for a given aperture and/or exposure time, the lowest ISO I can force the camera to select is 200.
Is this expected/wanted from the camera or is some other setting responsible for this?

This happens when you select any of the modes allowing the camera to make adjustments/corrections to the exposure. The reason is that the camera needs to have leeway for the adjustments. Therefore it does not allow you to start from the end of the scale.

Specifically you have highlight correction turned on. Turn that off to get ISO 100

Thanks! And highlight correction only affects the .jpgs anyway, right? So turning it off when I'm shooting RAW (or RAW+) has no disadvantages for me then?
