where do you "see them in green" on the player?
if you want them yo auto load when the track loads you must choose that in RB, Plug the drive back in, select all your tacks, click on the info pane on the left and then choose to "allow to autoload hot cue"
you can also set this in the preferences of RB for tracks you add to RB in the future
if you want to recall the hot cues without them auto loading you must hold the rec/call button down for 2-3 seconds until the cues you added start to blink, you can then press to load
