Pro DJ Link Troubleshooting

Hello,

I am trying to have my cdjs CDJ2000nxs and DJM900nxs2 connect with Pro Link. The Two CDJ2000nxs decks are flashing yellow and not turning solid green like the DJM900nxs2. Has anyone had this issue or know how to fix it? Thanks

 

Here is a quick video demonstrating the connection issue I am having.
