SeriesGuide is telling you that it can’t update the movie “Is Love Enough SIR”. This may be a temporary issue. If it persists, you can resolve it by removing that movie from all of your lists.
I suspect what happened here was that the movie had a duplicate entry with a different title in TMDb and the one that was linked in your list has been deleted. If you want to re-add it, this appears to be the same movie: Sir (2018) — The Movie Database (TMDb)
