How does a refresh works with TVDB?

How does a show refresh comparing it to TVDB site?

For example, the show: https://trakt.tv/shows/una-familia-de-diez it has 3 seasons and only 50 Episodes.
It says the Datasource is TVDB, if you go to the page there: Una Familia de 10 - TheTVDB.com it has 5 seasons and 76 episodes, which is the correct number.

How the Trakt page can be updated with that? AS it says Update August 2020 and if you click on refresh it doesn´t refresh anything.

There are two issues: there’s no English titles or images and there’s a duplicate listing of the show. I’ve put in a request with the developers for these two shows to be merged, but English will need to be added for the episodes to be imported/refreshed on Trakt.

*The rules are basically the same for TVDB except that images and people still come from TMDB.
