Create shape from vector layer problem

Good night,

So, I'm with a problem that I couldn't solve so far.

I've done my work on Illustrator and released all layers into sequence, for Afx.

The problem is: When I import the .ai file to afx and choose "retain layer size", works fine:

But, when I "create shape from vector layer" (the .ai files, in this case), they all lose its source size, like the image below:

The weirdest thing is that few files only retain the same size when I create shape from layer.

Hope you guys can help me. Thank you
