Question missing split washer in 2nd stage demand valve

[robinly]

Hi all,
I'm interested in regulator service recently, so I read a related book and watched some videos.
Today, I disassembled my B2 and checked parts with an exploded view, then I found that I did not have a part named split washer as marked in attached diagram.

I'm pretty sure I did not drop the washer by accident and I don't understand why it is displayed in exploded view.
Any advice or comment is welcomed, thanks.

Just so you are oriented correctly, the split washer in question is made from plastic. Double check it is not stuck against the end of the knob stem:

Know nothing about these regs,
But do know how to read a diagrams...
I assume the oring ahead of it... does it go on the knob stem?
Does the split washer backup the oring?
Sure it's not in the groove?
