Whirlpool confusion

Anyone have an idea where the ring seal in this image goes?

I was having issues with draining so I opened it all up. After opening it I now have a leak through the shaft and down onto the motor. So I ordered the impeller drain kit and the pump seal kit. Neither come with the seal that goes around the shaft. I noticed on this seal that there was a tiny nic in the plastic.
I then realized that item 19 comes with this shaft seal. But either way I still have this extra ring seal.

Does anyone have a close up image of this seal that goes around the shaft?
