Thanks Justin.
I had a look at https://www.themoviedb.org/tv/87012-the-great-british-bake-off/season/6/episode/3/edit?active_nav_item=external_ids and it appears that the external id is entered for TVDB over at The Great British Bake Off - Bread Week - TheTVDB.com.
Is it this 9330102 value that you would be expecting to appear in the scrobble data? I keep copies of the JSON scrobbles if that helps
