Thank you Fred! And thanks Axel!
Now that you mention it, it’s actually the stereo file that’s causing the problem. Now I see that if I’m viewing 1 of the 2 channels (using the “eye” icon at bottom left of the waveform interface), I “think” I’m looking at markers for just one channel but in fact it’s both.
If I do this with a monaural file, there are for sure no overlapping markers, and I can move them one at a time as I’d expect. The problem is definitely the stereo file, but the interface suggests that by isolating a channel, one can also manipulate markers placed only on that channel. Looks like in fact it’s always displaying the overlapping 1BEG markers for each channel in a multichannel file. Unfortunately I don’t see this documented.
Also, now it’s clear, as Axel wrote, that only the 1BEG markers are being displayed.
I should mention that in both cases (mono or stereo), I cannot click & drag to select multiple markers and move them as a unit, as you’ve described. Is there a modifier key you’re using? I’ve tried clicking and dragging, also click + shift + drag, but ultimately I can only move one marker at a time.
Also I should mention I’m late on these recent replies because somehow my notification preferences in the new discussion forum were reset! Sorry about this; I’ve just reset them again and I should for sure be getting emails whenever someone responds on this thread.
Many thanks to you all! —
