Strum Session 2: Must manually reload loop each project load?

Hello,
 
I open an existing project with the Strum Session 2 virtual synth loaded with midi data in the track for looping. To get it to actually play, I have to manually re-select the loop from the loops window--until then, no sound. (Keyboard and guitar modes work fine upon loading though.)
 
Does anyone have a work-around or know of a reason for this?
 
thanks!
