The only thing we could suggest is that perhaps the layer height 0.3mm and in particular the shell thickness of 1.2m is too thick for these delicate parts. On the images you have attached the only one that appears to be displaying incorrectly is the chimney and the roof for the chimney piece, however the others would print quite thick and not as delicate as required with those settings. Perhaps try 0.2mm layer height and the minimum shell thickness that your machine is capable of and slice it again.
