My stats says ive played 651 games and have 19.224 kills and lvl 777 which rlly doesnt add up is there a way i can fix my played games?
You ultimately need to add trackers for each of your legends one by one; it’s a little bit of a pain but is purely a limitation from Apex/Respawn not us. Follow this guide if you can
Tracking your statistics with ApexTracker - FAQ - Apex Legends - Tracker Network
so if i equip games played and kills and damage on every legend it will show the correct stats for those?
Yeah; a little bit of a pain for sure!
But you get used to it 
(Especially if you main one legend!)
