Stats and account linking info

so i have a PS5 i have linked on my profile my psn account, my battlenet, and but it wont allow me to add my activision account, HOWEVER if i look at my Activision acount it says i have 97 wins, if i look at my psn account it says i have 114 wins ( iahve 265 wins in total) so this is still wrong, however i have never used a different account iv always signed into CoD on my playstation as my Activision ID any idea why it does this and how to correct it?
