Exporting spritesheet to unity

[yinoni]

Hi there!
first time i use animate for this need,
and i have a unsolved issue...

when i export the sprite sheet, is seems to have a few lines of empty pixels in the bottom and to the right of the image, that unable for unity to cut is out nicely.

i checked the trim box, and choose 'auto size'.

what can i do to fix it?
