Ok as you guys can see, there's that A-PC history thing on top of the actual history. I'm trying to remove that thing since it's always stuck up there and also on recently closed tab, and it's always has the same pages. However, I have no idea how I made it like that so I have no idea how to remove it. Any help?

As the title suggest I'm using Google Chrome.

But I tried Google, but Google showed me tons of different results and most of them didn't helped/worked or didn't even involved with what I'm talking about. And I tried several searches.

maybe its because of your google account

"Collapse" and "Open All"

I even tried clearing history and stuff. The only solution I can think of right now is to reset the browser but I don't want to loose all my bookmarks.

I just tried resetting it, didn't work. I even tried re-installing it, but it created more...
