If you got to sign the Annex A means you have half on one page and half on other. In that case I dont think that it should be and issue. But I am not sure about just sending half with address and no signature. Some one who did that may reply and confirm it.i did same thing, because I could not change the email, and the print out result is showing half of ANNEX A. I think is fine, they just want to see our signature that Visa will be put in our passport. correct me if I am wrong
