Digital BW, The Print

I have just started using QTR and I like it .  One problem I have is that the 
presets don't stay when switching to other printers or switching from one 
preset to another.  I can make a preset with 50 cool and 50 warm....I can make 
variations on this say 40/60 and save as preset.  Now when I switch between 
the two presets the settings change back to a default???  What am I doing 
wrong.  Thanks Eric
