So I guess it's alby which is the lnurl and blue wallet is linked but is not actually a bluewallet lnurl address i.e. not bitcoinsandy@bluewallet.com
Discussion
bitcoinsandy@bluewallet would be a "Lightning address" Which is like an email address for your lnurl (which is an ugly, longform version). There was a post or graphic posted a few days ago that described this better, but it was nice to help with confusion of the words we use.
I am always available to confuse 😂
