FC 25 Xbox Issues

I play fc25 in xbox series s. Quick subs does not work. It requires to press RT for quick subs but it does nothing. When I controlled my buttons, RT is working. Another issue is the auto save in career mode. When I finished a match, I dont want to save my career and I select don’t save and exit. However it saves as soon as I exit match. It was not like that in Fc 24. Please can you help? Sincerely, Ramazan Aktas
