Matrix help

Can you tell me what I'm doing wrong? I have bounced my midi to audio, checked  enable groove clip looping when importing to matrix, dragged the clips in to the matrix. The first column is 4 bar clips, another column is all 8 bar, and another is all 16 bar.
 
The problem is they all play like mud, super slow.   A clue, however is that the 16 bar column is closer to the project tempo, but the 4 bar  clips are REALLY slow.
 
What little thing did I overlook?  and Thank you!
