Spring relocation kit installed wrong?

so I bought this car last summer and didn’t have much time to enjoy it, either way mid way through the year I developed a new clunk, looking under the car I noticed my shackles were pancaked flat against the frame, upon further investigation this car has had a spring relocation kit installed, now this got me to thinking that it may have been installed wrong, I also noticed that the rear shackle hanger is offset from the frame which most installs I have seen are centered on the rear frame rails

Hopefully someone can chime in and shed some light to give me a direction to fixing this problem? I’ve attached a photo with a measurement off the original frame location for the spring hanger to where the Center of the hanger is now, approx 4 1/8” if someone can reference their car for me to see what went wrong on mine
