[Metadata] TVDB 153841 / The Nanny (PL): seasons 1-5 return no episode titles from SkyHook, Sonarr shows TBA

[wojchal]

Sonarr version (exact version): 4.0.16.2944
Mono version (if Sonarr is not running on Windows): N/A (Sonarr v4 on Kubuntu, not using Mono)
OS: Ubuntu 25.10 x86_64
Debug logs: PrivateBin
Description of issue:

Sonarr shows TBA for episode titles for this series:

• Series: The Nanny (PL)
• TVDB ID: 153841

The issue affects at least seasons 1-5.

The series itself is matched correctly in Sonarr:

• correct series name
• correct season and episode numbers
• correct air dates / airing times
• Refresh & Scan completes successfully without visible metadata errors

However, episode titles are shown as TBA.

I checked the SkyHook response directly here:
https://skyhook.sonarr.tv/v1/tvdb/shows/en/153841

In that response, episodes from seasons 1-5 are missing the title field entirely.

Example from season 2:

{“tvdbShowId”:153841,“tvdbId”:2008881,“seasonNumber”:2,“episodeNumber”:1,“absoluteEpisodeNumber”:16,“airDate”:“2006-03-04”,“airDateUtc”:“2006-03-03T23:00:00Z”,“runtime”:25}

As shown above, there is no title field.

For comparison, later seasons do contain titles in the same SkyHook response.

Example from season 6:
{“tvdbShowId”:153841,“tvdbId”:3332791,“seasonNumber”:6,“episodeNumber”:1,“absoluteEpisodeNumber”:76,“title”:“Młodszy brat Maksa”,“airDate”:“2008-03-01”,“airDateUtc”:“2008-02-29T23:00:00Z”,“runtime”:25}

The TVDB website does show episode titles normally, for example season 2:
https://www.thetvdb.com/series/153841-show/seasons/official/2(opens in new tab)

So it looks like Sonarr is behaving correctly and showing TBA because the SkyHook metadata for this series is missing episode titles for seasons 1-5.

I already reproduced this with a Refresh & Scan and included logs.
Please check whether this is a SkyHook / TVDB metadata sync issue for TVDB ID 153841.

Looks like there were a couple things at play here:

1. A lot of episodes don’t have English translations (at least some that do aren’t really translated, they’re just using Polish)
2. TheTVDB’s API takes a little while to update and start exposing that information to Skyhook, the time seems to vary, but usually at a minimum we estimate about an hour, in some cases (more-so with their old API, it could be closer to 24 hours)

Looks like Skyhook has episode translations now, at least for the ones TheTVDB has.
