Uni2D physics stuck

Hi all,
I’m using uni2D physics. I have building that has many parts with Uni2D sprite with dynamic convex physics. And physics are set kinematic when it’s idle.

When the player hits that building, physics are being kinematic false and falls into parts.
The problem is: sometimes some parts are stuck in the air.
I can move one part from Scene then all stuck parts are falls down.
Does anyone has any solution for this?
Thanks in advance.

I just gave little timed shake to avoid this bug.

Use Rigidbody2D.WakeUp().
