Antiques Roadshow shows as series record in my schedule now so I may have be mistaken before and it may have shown as 0 episodes due to the next episode being a repeat from a previous series rather than a continuation of this weeks. Also I set series record for The Bidding Room BBC1sd , it only set to record a couple of episodes this week and one next and another schedule had to be set for the other episodes this week ( it airs Mon-Fri) all episodes show in the TV guide as repeats from 2 previous series but the episode recorded yesterday was S6E1 which is the new series as confirmed on IMDb
https://www.imdb.com/title/tt11434078/ . January 7th is far too late to blame error on festive excess.
Edit. Ignore the above, I now see that for some bizarre reason BBC are showing the new series on Mon, Wed and Fri with old episodes on Tues and Thu and TV guide now showing the correct episodes.
