If you click the associated link you'll see my active characters (from my xbox account); however, if I access this while signed into my account it actually shows my battle.net profile. Other users mentioned this on reddit in the cross-save megathread, so I suspect it's possibly site-wide or more than just myself impacted. Bear in mind, this does not impact the characters I'm able to use and is merely a cosmetic issue with the website which only impacts the player viewing their own profile. As such, it's not a major concern, but it definitely does cause some confusion and concerns when it's first seen by a player given that they may believe they enabled cross-save for the wrong account.
