S10 Episodes 29-41 can be deleted as they are from a spin-off show "Jack and the Sodor Construction Company" now captured here: https://www.themoviedb.org/tv/103701-jack-and-the-sodor-construction-company?language=en-US

S10E51 is a duplicate entry of S10E34 and can be deleted.

S10E42 Trouble For Thomas can be deleted as it is a US re-title of S01E06 Thomas & The Trucks.

S10E43 Thomas and Percy's Mountain Adventure can be deleted as it is a US re-title of S03E26 Thomas & Percy's Christmas Adventure.

S10E44 Knapford Station should be deleted. Can't find a reference to an episode with this title. Possibly an extra on a DVD but without further info I think it's best to clean up the entry by deleting it.

S10 Episodes 45-50 refer to special segments that have now been added to the Specials season, hence can be deleted.

Happy to be corrected on any of the above if I've made a mistake.
