I see what you mean now, you are reffering to the results page, not the live search.
It was because the search override was not activated, so the default search results were displayed. I've turned it on for you on the General Options -> Logics and behavior panel: https://i.imgur.com/lsoyc77.png
It's not enabled by default, as a lot of customers prefer using the default search or a different search plugin for the results pages.
For more info, you can check these topics in the documentation:
