When calling recording web service, I see that all releases where there is no release country don't show their release dates:

https://musicbrainz.org/ws/2/recording?query=rgid%3Ad1b6c6cc-32c1-4f12-a2a9-4201c65b28c9&limit=100&fmt=json

• In this /ws/2/recording?query call, the 979ab5a7-3796-43ac-aeb8-16837759a2c4 release.date and release.release-events are null
• In /ws/2/release/979ab5a7-3796-43ac-aeb8-16837759a2c4 call, the release.date is 2016 and the release events is OK.

The date source code seems not shared and seems buggy (when release-event.x.country is null) in /ws/2/recording?query

Similar problem:

• In this same /ws/2/recording?query call, the 26a3ccee-93cd-48a9-b250-08b94bf30e98 shows empty date, although it has many release events with date set, so why does it take the only release-event with no dates (XE)?
• in /ws/2/release/26a3ccee-93cd-48a9-b250-08b94bf30e98 date and release-evens are all good
