I circled where I think is mis-alignment.
Could be you didnt close the trunk tightly.
If you did, it's an easy fix though.
if you open the trunk, you'll see 2 plastic extension screws, I dont know what they're called, but they adjust how your trunk sits.
In your case, screw them in a bit so your trunk can sit a tad further down & the tail lights will align perfectly.
