The other crew kontainers have a "WOLF Crew Crate" module with a certain amount of economy/luxury passenger seats. The 3.75m Crew Cargo Kontainer's "WOLF Crew Crate" module has "Payload: 1". By comparison the 2.5 has 6 economy/3 luxury while the 5m has 30 economy/15 luxury.
I think this is version 1.4.0 - 2020.12.20 (via WOLF/CHANGELOG file).
