Anima2D Error question!

Hello Unity is the person who is studying.
I use anima2d, like the one pictured above
It is moving small characters.
But if you move the characters
What causes the error to appear like a picture?
I can not solve it by myself because I do not know what to do.
When I search Google, I do not have any information.
I look forward to your reply.
Thank you.

I have such a problem, any ideas what to do?
