Romaji differs from hiragana:

romaji => [q(), qw(Man Oku Chou Kei Gai Jo Jou Kou Kan Sei Sai Goku),
https://metacpan.org/source/DANKOGAI/Lingua-JA-Numbers-0.05/lib/Lingua/JA/Numbers.pm#L120
hiragana => [q(), qw(まん おく ちょう けい がい じょ じょう こう じゅん せい さい),
The hiragana goes Man Oku Chou Kei Gai Jo Jou Kou Jun Sei Sai but the romaji goes kou kan sei sai, with the difference being the "Kan" versus "Jun" pronunciation.
This question says that "kan" is the correct one:
