In one project, I was able to insert some time with no problem at the beginning of the timeline. It pushed all my events and markers to the right as expected. However, in another project, I'm trying to do the same thing, but it's only pushing the events. The markers are staying in place which is not what I want. I thought perhaps it was caused by ripple edit, but I tried it with it on and off and same result. What could be causing it to work in one project but not another?
