Increasing volume level in half track mode does not save

Hi Again, Folks,

   In my new version of Adobe Audition, when I mixdown to halftrack, and I increase the volume level there, it does not save.  If I have the levels right up to optimum in multi track mode and then mixdown to half track, and the level is up where it needs to be, it will save, but again, if I increase it at the half track mode, when I do a Save As, it will save it at the level it was at in Multi Track mode.  Is there a setting that needs to be changed so that when I increase the volume in Half Track mode, it will save.  What I've had to do is, take the wav of the mixdown, import it into a new project, put it in a channel (1), increase the volume there, then do a Mixdown To New File, so that the level is already up where it needs to be, then it will save.  In my old version, I didn't have this problem.  When I do have to increase the volume level, it's only slight - 1 or 2 db.
