There is not enough context in your question, I am struggling to understand what you are saying.
You say you have a "quick filter" for "Labels = Request". The JQL is clear and valid. As a quick filter, this will be restricting the board it is on to issues with that label (from the full set of issues selected by the board filter). But I do not know what you mean by "page filter"?
Also, what happens when you just run the same query as a plain search.
