Since updating Rush, I can no longer add gaps between clips. Lengthening or shortening a clip alsp adjusts the adjacent clips and audio - which I don't want to do at all. Specifically, I have subtitles which sometimes need to have gaps between them, to line up with the narration. Before the update, I could adjust each subtitle without affecting anything else around it. Now, if I shorten the duration of a subtitle, everything else moves, which makes it impossible to adjust and also impossible to add space between my clips. Please let me know how I can change this.
