Autofill on website when it shouldn't

I have an entry (test1) in 1pass that has 2 websites listed in this order:

https://AA.BB.example.com/CC     ← this is marked as never fill on this website
https://example.com     ← this is marked as fill anywhere on this website

The intention is that if I go to any URL in example.com EXCEPT for AA.BB.example.com/CC, it will fill in login/pw.   If I go to  AA.BB.example.com/CC, it should not fill in login/pw from test1.  I have another entry (test2) that is exclusive to that URL.

Turns out, when I do go to  AA.BB.example.com/CC, it is filling in from test1.   I tried switching the website order, but no change.

Am I doing something wrong?  Or misunderstand how this should work?

TIA
