MachFive loops won't sync to master tempo

[jbasscase]

I'm new to this, so maybe it's something silly... I've got MachFive 2, running ProTools 7.3.1 on a G5. I've been able to run all my garageband loops through MachFive and they sync up fine, but when I try to use any of the loops that came with MachFive, they won't sync up tempo-wise. The sync button in the Loop Transport area is on. What am I doing wrong? I read the FAQs on Motu's site and it said "Set MachFive to sync to your host tempo, and any loops set to "tempo" or "pos" mode will automatically sync as well" What does "loops set to tempo or pos" mean?

Anybody? Please? I've written two "techlinks" to Motu and have had no response their either. This is bumming me out!

When a loop is loaded in LoopLab, there are two places to set the sync mode:
1.) Along the right side of the window, under the Master & Part settings. This is always visible. See screenshot on p. 117 in the manual.
2.) In the bottom right of the expanded LoopLab view (click the expand button in the upper left corner of the waveform display). See screenshot on p. 102.
In either place, you'll see a "Sync" label next to a drop-down menu.
