Unexpected rendering 'author field' in 'rawImports=true' mode

[unknownnumbers]

I want to import bibtex data with latex mode without any change. But it seems that in this mode('rawImports=true'), the author field is single field instead of double field. I want to set the default format of the author field to be double field as before. The reason why I want to maintain the format is to maintain the citekey format. A simple example and difference is as follows. What can I do? Any suggestions and hints will be appreciated.
