Ignored Friend Requests Don't Disappear from Notifications

Today when I went to clear my Friend Requests inbox of bot requests. After the whole lot was cleared I opened the notification tab to remove the Unread dot. However upon opening it I was met with this.

Now the 3 notifications are seemingly normal. The only thing is: I don’t have any incoming Friend Requests from any of these users! I had ignored all of them because they are bot accounts.
Plus, when clicking the ignore button on the cl1ks request. When refreshing the page or switching to a new one. The request automatically returns into the notification box! As if it wasn’t accepted or declined.

To add further information: I am not running any extensions, and my browser is currently Opera Version 57.0.3098.116.
