I checked the statistics with the one on MyAnimeList and they match. Note that the scoring may not match for other services such as Kitsu and AniList as the scores are converted to a 1-10 scale. This will only be the case with scores, everything else should match.
Can you elaborate which statistics are not correct. If it’s not correct, it’s probably because the list is not recently synced from the remote service to the local one.
