Reply to Samples wont save cant load samples into sample deck

Hi Guys,

i have a macbook pro.
i am importing sample paks into the track collection and the samples are there i then go to the remix sets and the title of the sample pak is there but no samples. I have made my own sample paks and again the title is there but no samples are behind the title.
Must be something simple but i am missing it.

please help me out here thanks.
