Not every queen cell means the same thing, and mistaking one kind for the other is one of the most common beginner errors.

A single cell, built centrally on the face of a frame, usually means supersedure: the colony has judged its own queen failing and is quietly replacing her without any intention of swarming.

A row of several cells hanging along the bottom bar of the frames is a different message entirely, the unmistakable sign of an active swarm plan already underway. Beginners often see a few cells and decide they are not urgent, or confuse a bottom row for a stray supersedure attempt.
