Piece size matches selection

Artwork dimensions must match the selected trim size (bleed of up to 0.125" per side allowed).

How to fix it

Export the address side at the exact trim size, or trim size plus 0.125" bleed on each side. A 4x6 card exported at 4.25x6.25 with bleed is fine; 5x7 is not a 4x6.
