I have the same problem, but it seems to affect more than just new fingerprints.
A bit over a week ago, I created this release: https://musicbrainz.org/release/802262e8-aa5c-4676-b71e-1b212e2d3b7b.
Before creating it, I scanned the tracks for fingerprints with Picardand only the second track came up as a known fingerprint. So when I was creating the release, in the recordings tab, I connected that track to the known recording, while leaving the other tracks blank so new recordings would be created for them. When the release was created, I loaded it into Picard, scanned for fingerprints and submitted them for the unknown recordings.
On MusicBrainz, all the fingerprints are displayed as normal (eg. for the first track: https://musicbrainz.org/recording/01afe5ba-7516-4308-bb12-68fdfbc49aae/fingerprints), and the second track also seems to be correctly linked with the pre-existing recording (https://musicbrainz.org/recording/315e3b52-eb1c-436b-8029-98c061af921e).
When I scan these tracks in Picard, with the album I created already loaded:
- the previously unknown tracks get loaded as non-album tracks
- track 2 gets loaded in the album with the pre-existing recording
After dragging and dropping the tracks onto the right album, the button to submit fingerprints doesn’t become active and all the fingerprint icons are black. So Picard correctly recognises the link between the tracks, recordings and fingerprints.
On AcoustID, the previously unknow tracks all show just their MBID, like Alioth also described.
I also created this release on the same day, as a different version to a pre-existing release: https://musicbrainz.org/release/ca5763b3-924f-49d6-8393-84cb831e3985.
When scanning before I created the release, the pre-existing release got loaded, so the recordings on both versions matched. After creating the release (making use of the pre-existing recordings), I loaded it into Picard, dropped the tracks on it and saved.
When I scan the tracks now, Picard still loads the pre-existing release, even if the release I created is loaded already.
And adjusting my release preferences doesn’t help: I set them up so they would target specifically the realese that I created, with preferred release country only “Germany” and medium only “cd” selected. Yet Picard still loads the worldwide digital media release.
The issue also affects merged recordings. For example, I merged this one last week: https://musicbrainz.org/recording/2f04ea02-cc8a-478c-94fa-f27c31c76095 (merge was completed 2 days ago). On MusicBrainz, both tracks are now linked to the same recording.
However, if you follow the links to AcoustID for the connected fingerprints, the first fingerprint is connected to 1 recording, while the other 2 fingerprints (https://acoustid.org/track/dd9a7dd9-f33e-49b7-96fa-bd5cbbfb50e3 and https://acoustid.org/track/74cf9ae6-3c5b-4d1e-b3fc-202efa4fc26f) are connected to 2 recordings (https://musicbrainz.org/recording/da37e45a-741c-4452-9734-61343cd34d5f and https://musicbrainz.org/recording/2f04ea02-cc8a-478c-94fa-f27c31c76095). Following the links from the recordings shown on AcoustID, leads you to one and the same recording on MusicBrainz. da37e45a-741c-4452-9734-61343cd34d5f was the MBID of the recording that got merged into 2f04ea02-cc8a-478c-94fa-f27c31c76095. So while they are merged on MusicBrainz, they stay separated on AcoustID.
