Windows 10: Personalisation Intermittent Changes

Hi Folks, on my old, still used occasionally Win 7 Home Premium 32 bit desktop pc, I have set the background image to change every 30 minutes and it works perfectly. I have 360 images. On my newish Win 10 Laptop, I have tried the same and failed completely. It can be set to change every 1 Minute, 10 Minutes, 30 Minutes, 1 hour, 6 hours or 1 day. If I set it to change at any interval except 1 Minute it will change the image twice, 10 seconds before the on the minute of which one I have set it to use. Never used 6 Hour or 1 Day setting.

Cannot use Settings->Personalisation to change Lock Screen settings

Hello,
Is it possibly the Anniversary Update, which has blocked my possibilities to change the Lock Screen configuration? In Settings->Personalisation that whole option is greyed out today and I'm stuck with a lock screen, which I can't modify or change. Any help for this? Perhaps there is a registry change I could apply? I would be happy for any suggestion.

I've attached an image. My language is Swedish, but I guess that you will recognise the part of the Settings->Personalisation, which is shown.

Thanks in advance
