CDJ 3000 doesn't read the playlist but works on CDJ 2k Nexus 2

Hello, my friend has a WD elements ssd hard drive that is using. When he connected to my CDJ 3000 it didn't see the playlist names only the tracks which is ver enjoying. After 15 minutes a CDJ 2000 Nxs 2 arrived and it worked fine on that. Can you please tell us what this could be?
