Man with 5 hands or how remove hands / reset tracking

[MrMortis]

In some cases, Leap Motion can track many nonexistent hands...
For example: Leap Motion tracked my hand, I touch my face and put hand behind back, than Leap Motion think that my face is hand.

How I can remove hands?
I mean, that Leap Motion Device must forget some hand.
Or maybe exist way to forget all hand?
Or maybe exist way to check tracked hands(refind them)

I know, that I can:
1) Restart service https://support.leapmotion.com/hc/en-us/articles/223784008-How-to-Manually-Restart-Leap-Core-Services
2) Close Leap Motion view by hand
3) Disable GameObject in Unity

But it's not accurate solutions or poor for performance.

You can certainly set a limit on how many hands Unity will render -- but the Leap Motion Controller's tracking isn't really optimized to track hands from the floor.
