The error is located on the box and refers to a 501st Officer Minifigure and the positioning of the blue range finder antenna. The box render gives the impression the antenna connects to a lower point than the physical element can actually be attached to.

Thankfully it doesn’t hinder the elements inside the box or the overall build experience. Read the office statement given by LEGO below.

Jens Kronvold Frederiksen, Creative Lead for LEGO Star Wars said:

“Creating new sets involves a number of different teams working together in parallel, and unfortunately in this case the printed box art for 75345 features a computer render of a Phase 2 Clone Trooper helmet that doesn’t reflect the final finished physical element and positioning of the range finder on the figure.

In the final design of the physical helmet element, the visor dictates where holes for extra attachments need to be placed for them to sit. This is slightly higher than the position where the range finder is on the render found on the 75345 box.”
