News Feed - all Top News is duplicated multiple times

All of my Top News on the News Feed page are listed multiple times, some up to 6 times. Is there a way of controlling this? Even if I hide the entries, they are displayed again when I refresh the screen.
The Most Recent screen does not do this.

They may have gotten duplicated when you were trying to scroll down. If you clear your cookies and cache, does the issue persist?

I cleared the cookies & cache, same problem. I scroll down and the feeds just keep on being replicated until when I finally get down to the bottom I'll have multiples of every post. Even if I try to Hide them, they'll come back, and sometimes in multiples again so that where I had 3 at the start, I could now have 5 or 6. Annoying.
But only in Top News; not Most Recent.

I've had that problem before too, but it goes back to normal after I reboot my browser.

Since that hasn't worked, please report this issue to Facebook [You must be registered and logged in to see this link.] as they may be able to help.
