Rekordbox ID Tags

I am using a program Music Tag Editor Pro.   I am cleaning up titles and genres in my collection on my hard drive.  I have renamed and edited all appropriate info.  However, when I bring the files to the Rekordbox form the file folder, its placing the artist name next to the title instead of in the artist column.  This makes no sense since the artists names appear in the the correct area in the file folders and any other tag editing program I bring them into.  What is happening that RB is not translating this correctly?
