Pella Storm Door Mortise latch set

I ordered the item # 40-198 mortise for my Pella storm door. The latch received looks the same and fits the same as the part I am replacing, however the part received has a slot for the deadbolt actuator to pass through while the part in my door has a large keyhole shaped hole for the deadbolt actuator knobs.

The dimensions are identical. Where the deadbolt latch passes through, there is a black bushing with a slot through it on the item I bought. The design of the one on my door has a keyhole shapes hole passing through the mortise. The attached picture shows my door hardware and the shoulder that the deadbolt latch is on is the size and shape of the cut-out in the mortise.

Thanks! Take a look at our 40-194. That could be the latch you are looking for, based on your picture and what you describe.
