I work on an XAVCH project. Media were imported via Link To Media and Transcode. I removed the empty tracks D1, A3 and A4 on the timeline.
I must have made an unwanted action during editing. Now the timeline header shows again all source track buttons D1, V1, and A1-A4 on the left side. On the right side are the editing track buttons V1, A1 and A2.
I only wish to keep the latter ones. How can I hide all the source track buttons?
