I believe dataclasses uses repr() of the members, not str(). Can you try using 
specifying __repr__ in Teacup? Just __repr__ = __str__ should work.

[issue46693] dataclass generated __str__ does not use overridden member __str__

[Bruce Eckel]

New submission from Bruce Eckel :

When creating a dataclass using members of other classes that have overridden 
their __str__ methods, the __str__ method synthesized by the dataclass ignores 
the overridden __str__ methods in its component members.

Demonstrated in attached file.
