Rekordbox track problems

Hello,

I currently own the Numark Mixtrack Pro 3, and I'm planning on buying the XDJ-RX2 soon, so I want to ready up by analysing all my tracks. But for some reason my tracks don't include the key, artist, album or anything else (They do include BPM). also, beat grid which is displayed over the track isn't lined up correctly. the white lines are on the beat, but the thicker white line with the red dot on it isn't on the first beat of the song. Both problems don't really block me from DJing, but I just want to know why this happens and how I could fix it.

Thank you
