I'm having a little problem in Illustrator CS6 that makes me very confused.I'm trying to extend my file to the "bleed" grid,but the extended background is transparent,which then results in a blank space bleed.How could i fix it,it only happens with this file?[![enter image description here](https://i.stack.imgur.com/J4aML.png)](https://i.stack.imgur.com/J4aML.png)
