You have the first exit at 6 seconds and the second exit at 3 seconds. This will jump.
I cut the video at six seconds to accommodate your first exit. With your second exit set to 3 seconds, there will be a 3 second jump. Set your second exit to 6 seconds as well.
There will also be a glitch if you left trim the freefall but this is a bug. Your issue is normal behaviour.
