@smeeding2535 I'm not aware that there is any such thing as newenginevivaldi or New Enginevivaldi. When you add a new search engine to Vivaldi, you are supposed to replace "New Engine" with the search engine data that applies to the search engine you are adding.
Vivaldi does not have a search engine, and there is no search engine named Vivaldi. So what you have created appears to be a completely fictitious setting which cannot work.
