When a Lens is used in a search and answers are showing, if you request Quick Answer, there is no Quick Answer shown.
Another way to see the issue is this: if you already select a Lens before you write your query, then you write your query followed by a question mark "?", the lens works, but the quick answer is not shown, only the empty box of it.
I am expecting to see two selects out of one query: both Lens select and the Quick Answer select. Or at list I'm expecting for the Quick Answer box not to be empty.
