Product variables structs are generated at runtime to contain only the properties that apply to the current module. Defaults modules always contained all product variable properties. Defaults modules apply their properties to the target module using proptools.PrependProperties, which prepends structs that have matching types. Filtered property structs had a different type and were dropped. Even after adding filtering to the defaults product variable properties, defaults modules may contain more property structs than the target module they are applied to, so the product variables struct for the defaults module could contain more fields than the product variables struct for the target module. Use proptools.PrependMatchingProperties when applying defaults of product variables instead, which will apply matching properties across types.
