My stats are showing up as someone elses

I recently changed my nickname on my epic games account. When I went to go check if my stats transferred over I saw that the ranks, goals, saves, games played and everything was so different than my actual stats. I changed my nickname into one that someone had in the past and I think that the stats are being pulled from the person that used to have this nickname. The nickname is “Hexxiio” and I changed into that nickname about a month ago. Any help will be appreciated.
