Woah! Diane you ARE correct. I was about to reply to the contrary, but took a second look just now.
That is not only interesting but disappointing.
When I did the steps I mentioned above, I had also gone back to Subscriptions and it was gone (even after removing from blocked).
But like I said just now, taking that second look before posting this reply, I see it is now back.
It's interesting/disappointing because I would've expected that any entry in "Subscriptions" would occur by any NEW mail that did NOT go straight to junk.
In other words, that one entry I can see being added to Subscriptions when it managed to sneak by the failed filters.
My expectation would have been that once I moved it to junk (ideally it would've been removed from Subscriptions too by this task), then by removing it from Subscriptions and from Blocked, no entry would be added back unless that spam made it past the filters
in a NEW email.
It's looking like when the Subscription entry is "blocked", the entry still exists on the back end, but just not made visible. Making it blocked puts the entry in Blocked and "if entry is in Blocked, then entry in Subscription is hidden" (aka, not removed).
Yup, I just did those steps again and the same thing (which included "Save", which I didn't mention).
It was only when I left Settings then went back in did it show again.
