I selected multiple clips in a audio track, selected the first one, then scrolled to the end of the track, held Shift and clicked, all selected.
Then I went to the menu bar, Audio Effects, Amplify, Apply to All, choose, the Amount i wanted amplified, 150, close it, the only track that is amplified to 150 is the last one, the rest are at default, 100.
Ugh.
