Cannot delete titles from lists

Somehow I cannot delete titles from my lists. I tried clicking "Not interested" and "Remove" and when I look into my list, it's still there. To be honest, it's annoying at times.
Could it be that my browser is the problem? I am using the Chrome browser.

You want to remove movies/people from a list?

Click on the list then at the top you will see "Rearrange List" from there it will redirect you to the edit page then just click the small X at the bottom of the titles you want to remove from your list.

Yep! "Remove" is for unlistng an item from your "Collections", not from your Custom lists.
Deleting an item from your Collections means that the rating you gave is deleted, and the item will be unmarked as Watched, Wanted, Liked and so on.
