Missing Architectural parts .xml

By default the UK dataset is delivered with the Architectural_parts.xml

This seems to be missing from my install of Version 5 Open Buildings

All the other parts are all there such as :

Architectural Spaces_parts.xml

Electrical_parts.xml

Fireproofing_parts.xml

IFC_parts_si.xml

Mechanical Spaces_parts.xml

Mechanical_parts.xml

Structural_parts.xml

Has anyone else experienced this.  Apart from importing a new Architectural_parts.xml file to the parts folder, is there anything else I can do to rectify this?
