Hey there. You currently have an XBox account linked to PSN here on the account you are posting on. Are you trying to set Cross-save up, and it is not letting you authenticate XBox? Try logging out of Bungie.net and log back in using your XBox credentials, If it takes you right back into this same account, then XBox will be auto-authenticated on the cross-save screen. You should just need to authenticate PSN. However if it logs you into another Bungie account, or asks you to create a new Bungie account, or asks you to link an existing one, then it is a different XBox account to the one linked. But since you just linked it, I assume it's the right one so hopefully the above will work for you.
