SC5000 Prepare List Link Issue

I’ve been frequently running into this issue where whenever I add a song to the prepare list on a player, the song does not appear in the prepare list on the other player. This means that the two players have their own separate prepare lists, instead of just one shared list between the two of them. I know that link is working, because I play off of one USB, but I have no idea why the prepare list isn’t updating. Has anyone else ran into this issue? If so, did you figure out how to fix it?

Is the other player on the same source? Prepare list from different sources are not merged. I made a request back in time.

No, it’s all the same usb.
