Episode ten of series one, was not broadcast on 30th January 2021. The official BBC website for the program lists series 1 as only having 9 episodes (including the Christmas 2020 special). The currently "missing" episode 10 could be several things - a themed special episode yet to be scheduled, a compilation of unseen extra material, possibly a celebrity or contestant has passed away, or the episode has been held over for the start of season 2 to use as a stockpiled "buffer" episode if covid restrictions cause pre-production issues, such as contestant selection,etc.
