[GUI Plugin] Quality Check
See the option Fix ==> Swap Author FN LN <--> LN, FN
You can bulk switch all authors to use the proper author format.
Currently your authors (according to the image you posted) are in LN, FN format in the authors field. Authors expects to see FN LN, and sorts using author_sort which calculates LN, FN from the authors field. Once your metadata is fixed, it will display properly.
