Hey John,
Sorry about this. It’s a bug that has since been fixed for the next release. In the meantime, you’ll need to record with Start at Current Timecode On. I realize that’s inconvenient if you want everything at 0, but you’ll need to do that and then move everything back to 0.
Here’s the ticket in case you want to track it (it’ll be made publicly visible soon): Unreal Engine Issues and Bug Tracker (UE-176975)
