After the Switch Sound Format Converter completes the conversion of WMA files to mp3 files, I usually don’t input any tag into the Genre field. Nevertheless, when I don’t input a tag and when I later view the converted files detail using Windows Explorer, the Genre field will show “(148)”. What does (148) mean? How can I prevent Switch from automatically putting this “(148)” tag into the Genre field when I want the field to be blank? Thanks.
