how to stop address bar from remembering my previous entries?

for example, if I just enter "d" into my address bar, the address "dailymotion.com" will show up unless I type another letter afterwards that is not "a", such as "e". I used to visit dailymotion.com, but I just cleared all my history. dailymotion.com doesn't show up when I enter it in my "search history", yet this suggestion keeps showing up. How do I get it to stop?
