Yes, this is a known bug. Chris has pointed this out previously. It has been fixed in an SDK update.
Thanks for posting the details you did.
In the Meeting scene, it gives you the option to add dialogue, but the option to add a pause after the dialogue is no longer there. It was a super useful feature, would love to see it restored. (There is an option called "Delay before start", but you cannot move it from -1)
