Why is it that when I search for something, then click the duck in the top left corner that brings you back to the homepage, that instead of bringing me to the normal Url, it brings me to: https://duckduckgo.com/?t=i  which looks exactly the same. Further more when searching for something, for example "test" the url becomes https://duckduckgo.com/?q=test&t=i instead of the usual https://duckduckgo.com/?q=test
