I will figure it out in time I am sure but in the mean time something else has happened and I don't know why, the amplitude adjuster I usuall see when I select a part of a recording in the edit section mot multitrack is missing this is what it used to look like....
Now it is gone and can't remember how I got it in the first place here is what I see now

i have clicked Amplitude where i can find it but do not see anyway to get it to be pinned when I select a section or for that matter the whole waveform. Sorry to be such a dork
View menu>On-clip UI - put a check in that, and it will come back!
