Bosch wiper blades with spoiler

I fitted a new wiper blade today with one of them new fangled spoilers on. The spoiler bit is below the blade the way it comes assembled from the factory, doesn't feel right to me, especially as half the spoiler is under the wiper arm. Is there a right and wrong way for these? I think the spoiler bit is reversible, if it is currently wrong. TIA, Brian

Probably worth posting an image, not sure about the effectiveness but suspect the spoiler effectiveness is reliable on amount wind hitting the windscreen and tautness of spring

The spoiler blade sits downward almost vertically, perpendicular to the direction of wind/travel, and this applies more force onto the blade against the glass, and reduces air getting under the blade, which can cause lift-off and judder.
