OK so I was doing something earlier and I looked on my history as I always do, and found that history I deleted earlier, was still there. I was on the 'History' tab when I found this out. Then I went on the 'Show All History' tab and the history that should've been deleted was gone and the history that should be there, is there. The deleted history only shows on the 'History' tab. And another thing is that when I go on websites for help, the new history for those isn't added to the 'History' tab but to the 'Show All History' tab. I find this quite strange and annoying, could someone please help me? Thank you.
