Same bug. Add time signature alone. Did you find a solution?

Hi Matt. There doesn't appear to be a way to select them all at once, no.

Try this...

1. Select everything in the song, all clips and automation, etc.
2. Drag it all to a new empty scratchpad, directly, not via Arrange markers.
3. Go back to the main timeline, draw a selection range across the entire space and Delete Time which should remove all of the time signature markers.
4. Put the other clips back there.

Or, if there are no clips there yet like in your picture, just Delete Time.

any solution for this bug,?

I was moving around some parts with time signature changes in a project and ended with a bunch of bogus extra time signatures all over the place

Is this seriously not resolved? Sony Acid could do this in 1991.

Right click on timeline. Then click on loop follow selection. Drag the other marker to the end where you want the time signatures deleted. Right click on the timeline again then click delete time in loop. All the time signatures should disappear.
