Issue with Curve Filters | Cleaning mocap data

Hey! I’m trying to apply Curve Filters to clean animation data. As an example, the image below shows the part that I’m trying to smooth.

However, once I hit apply, the results are far from expected.

I’ve tried with many different values for the filter, but non of them worked properly. I’m new on Unreal, so I’m probably missing something.

Thanks in advance if anyone knows the answer!
