VST Transit - midi or audio parts on duplicated track of a different owner is still locked

Hi,

I am trying out VST Transit with Cubase 11.0.20 PRO. My understating was, in order to edit parts on a track owned by a different user I must duplicate the track. However duplicating tracks gives me parts which are locked. Why is this happening?

Edit: Found a solution. Duplicate tracks need to be unlocked manually by using a lock feature on a track (not in the lock function in the info line at the top), for which I had to reveal a button, which was hidden by defaul. Very confusing .
