finale 26.3.1.520

Again, I am having difficulty with the tempo variations in human playback.  Yesterday, I completed a piece, inserted all of the ritards, dynamics, etc, and they played back just fine.  I'm now working on a piece, inserted a poco rit., rit. molto rit.  and none of them changed the tempo.  Cleared all of the midi info for expression and no change.  I totally understand how there can be bugs in a program, but the inconsistency is killing me here.  As far as I know, I haven't made any changes to any software, and now it's not working. 

Help is greatly appreciated.
