Lifetime kills apex psn not matching with in game stats

hey there

i am new to this site and this forum.

i have realized that in apex legends on playstation in game it says i have over 9000 lifetime kills but on your tracker site it only shows 6002 lifetime kills. the legend kills for my main legend is correct but my lifetime stat is not. what can I do or can you help to fix it?

thanks for your help
