Cannot unsubscribe from news notifications

I don’t want to get notifications about new articles in the news feed. There is this little bell icon where you can select which games do you want to get notified about, and I deselected all, but I still receive the notifications. Every time I when I check again, it is not deselected, so basically it looks like you unsubscribed but in reality you didn’t.
I would really appreciate it if this got fixed.
