I'm new to Quran.com but I believe that there is an error next to the name of each prophet other than Prophet Muhammad (SAW). Instead of 'Alai Alsalam' being written next to the names of the other Holy Prophets especially in the foot notes, 'Salallahu Alai Wali Wasalam' is written. As far as I know, that is incorrect. Kindly check this. I may be wrong, Allah knows best.
JazakAllahu Khairan for your efforts.
