Problem with illustrator file

Really weird when I open my file as a pdf it looks regular but when I bring it back into illustrator to keep on editing it, its coming up odd. The coloring is not right and this grid that I cant figure out how to get rid of.
Any ideas?


Its a perspective grid. You can close it by pressing the x top left.

its not closing I will try again. And thats whats causing the colors to change when I open it?

Thankx I googled it, got rid of it but that was so weird because I had to fix all the coloring after.
