The penpa link appears to be incorrect. I.e the given digits are in the wrong place

This idea of using XY-Sums in absence of XY-Differences is entirely yours, but I'm flattered by the comparison! Very nice puzzle!

My apologies for the mistake. I was busy during the day so after putting it into Penpa I left it there. I started to solve it just now and quickly realized something was wrong.
