Unable to change lock screen types, 'clear credentials'-option greyed out



Hi there,

I am using the simple swipe unlock method, but often that also unlocks your phone in your pocket. When it did unlock it did something and now I cannot change my screen lock type, when I open settings>lock screen>screenlock it asks for 'Confirm PIN', while I never set a PIN. I tried all the ones I would possibly have set somewhere, but it doesn't work. I read somewhere that there are other people unable to change their lock type, and the solution would be to clear credentials, however, that option is greyed out.

I deactivated and activated device administrators, I cannot encrypt and decrypt my phone, as some people suggest, because it then also asks for a PIN.

Does someone know how to tackle this problem without a factory reset?

I have a SM-G900F with android 6.0.1

Thanks!
