Defender is Still Scanning Weekly and sending Report though Turned Off

I’ve disabled all scanning options in “Dashboard > Defender > File Scanning > Settings” section, but it’s still saying that I have Weekly Scanning enabled. Even, it sent me a email report Yesterday which was not supposed to happen.

Moreover, the “Change Schedule” button in “Security” Tab in the Hub, is also not working.

How can this be fixed?

Also, when I go to “Dashboard > Defender > File Scanning > Reporting” section and scroll down, the button beside the “Enter a username” input field is broken on my site.

Rupok said over chat that this is happening for translation. Can this be fixed too?
