I have an address that is no longer linked to any user. It was linked in the past, and it was added to a mailing list while linked. The link between the user and the address has since been deleted.

addresses/bbulger@ozone.arc.nasa.gov returns:

{#8911 +"email": "bbulger@ozone.arc.nasa.gov", +"original_email": "bbulger@ozone.arc.nasa.gov", +"registered_on": "2026-10-13T17:18:35", +"self_link": "http://localhost:8001/3.1/addresses/bbulger@ozone.arc.nasa.gov", +"verified_on": "2026-10-13T17:18:35", +"http_etag": ""99abfe09ad3d856eeda533f0b375c0b656d7d346"", }

When I look at the roster of members for my list - lists/eureka.espo.test.nasa.gov/roster/member - there is an entry for this address

  {#8903
    +"address": "http://localhost:8001/3.1/addresses/bbulger@ozone.arc.nasa.gov",

    +"last_bounce_received": "2026-10-13T17:18:36",

    +"http_etag": ""f6eaf8c4a7742973f66002122fdd2f08a64259d9"",
  },

But if I query for the memberships of that address - addresses/bbulger@ozone.arc.nasa.gov/memberships - there are no results.

Is that a bug? Am I misunderstanding something?

I can find subscriptions for the address with members/find querying on subscriber

{#8854 +"address": "http://localhost:8001/3.1/addresses/bbulger@ozone.arc.nasa.gov", +"bounce_score": 1, +"last_bounce_received": "2026-10-13T17:18:36", +"last_warning_sent": "0001-01-01T00:00:00", +"total_warnings_sent": 0, +"delivery_mode": "regular", +"email": "bbulger@ozone.arc.nasa.gov", +"list_id": "eureka.espo.test.nasa.gov", +"subscription_mode": "as_address", +"role": "member", +"display_name": "", +"self_link": "http://localhost:8001/3.1/members/a77bbc4067fa40fdb74cde507f323d89", +"member_id": "a77bbc4067fa40fdb74cde507f323d89", +"http_etag": ""f6eaf8c4a7742973f66002122fdd2f08a64259d9"", },

So the immediate issue looks to be handled OK. I am just curious.

Thanks.
