Since you mention using Piano Roll, I take it that the track you wish to transpose is MIDI.

From what you describe, it sounds like the track regenerates each time you re-open the song. To solve this, after you've transposed the track, freeze it. That will lock the transposed notes in place.

Alternatively...

The Soloist and the Melody tracks are the ones that transpose individually. With this in mind, and if the track is neither the Soloist nor Melody tracks, use "Edit | Copy Special | Copy/Move tracks" to transfer the track to either the Soloist or Melody and then transpose it there.
