Describe the actual behavior

Similar to #4436, I was not able to make any of those blendshapes value greater than 0.05.

Describe the expected behaviour

These blendshapes should have values greater than 0.05 when I sneer my nose / raise my eyebrows.

Standalone code/steps you may have used to try to get what you need

Official Python example code can reproduce this issue.

This could be a problem with the diversity of the model's training data (I am an Asian male).

Unfortunately this is still a major issue that noticeably decreases the quality of blendshapes face landmarker returns. The landmarks are great, but a large amount of blendshapes are inaccurate or barely go above 0 :/
