Fusion Animation not working after updates!

Hi,
I've been working on some basic animation and following the recent updates the animation doesn't actually finish properly? My keyframes are set to gradually fade out, however the ending just cuts short. I fixed this issue yesterday by reducing the animation in duration, however I've loaded the project back up and it's back. Really frustrating, as it took some time to get it back!
Any advice would be greatly appreciated.
