Not a bug
Didn’t get s firmware email for 2018.20.5 for S/X which should have come out 5/31 8 am ish
I have both checkboxes checked and I just got the email for the 3 version at 3:30 am on 6/1. Very weird.

Figured this out.. we already got emails for 2018.21. Arg. Not sure how to fix this when an intermediate release comes out!
Yes, it will only send out notifications of a later version.
