All samples from Groove Agent show up in audio folder

I record drums 13 tracks and use Groove Agent. I just upgraded from Nu 12 to 14. What I used to do was clean files and have only 13 tracks in the audio folder. Then I would go to the project open just the audio folder, not the program, and copy the 13 tracks and then send to a client. I noticed now when I do this, I have 101 samples from Groove Agent in the audio file and have no way of really getting the 13 that I need without going sample by sample. Never had this before. Appreciate any help.
