BiaB Ver. 2012, latest build.

Assigned Guitar R/T # 866 to "Strings" of a song.

The "A" part of # 866 is a palm-muted type thing.
And "B" is a hard power chord down strum.

The song has eight bars of A and then eight bars in B.

Song and the guitar part start out fine with "A."
Then it goes to "B" just fine.

Then, in the next time through the chorus, # 866 guitar stays in its power chord mode, it doesn't revert back to the palm muting.

What's up? Thanks.
