I load audio wav files into powertracks and then work with the volume sliders in track view to balance the volumes before rendering. Usually I can move the sliders back and forth to adjust a track and then play everything to check balance between tracks and maybe move the slider again if needed. Every once in a while a tracks slider will move back and forth on its own when I play the project. So I assume some how I am creating automated volume moves, but I don't know what I did different that causes this. Also is there an easy way to delete all automations. Did not find a clear answer in the manual. I am using I am using version 2020 in windows 10
