I'm sure this was always OK in the past, but just recently I loaded an instance of Kontakt on to a track and used the Alicia Keys instrument. All going fine so far. Then I loaded another instance on to a new track. I was surprised to see that when I opened the VST it was already loaded with Alicia Keys as the instrument. I changed this the a factory strings instrument. But this also changed the instrument on the other instance. I seems I'm using the same instance.

Am I doing something wrong?

Thanks
