My phone won't delete my search history to one site(Android)

[Android Central Question]

I've tried deleting my whole search history permanently, but it doesn't seem to work. When I hold down on the webpage it comes with the following message: "This is a web page that you've visited before and it's related to what you're typing." I've tried un-syncing everything and removing my search history without luck. It appears to only be there inside the google search bar widget thingy.
