So many questions about a show that may or may not exist

My wife likes the band treaty oak revival. I've never heard of them which doesn't matter since the band itself is irrelevant to the thread. She saw online that they play in Birmingham on December 26th and wanted me to check out tickets. But I swear it's like I'm being punk'd because some sites appear to verify this information, while others have absolutely nothing. Here's a quick rundown.

-If you go to stubhub it shows them playing on 12/26 at the coca cola amphitheater downtown but it's "sold out". Never in my life have I seen an event on stubhub that literally doesn't have a single ticket available, considering it's a resale site.
-If you go to the coca cola amphitheater actual website, this concert is not showing on their event page.
-If you go to the band's official website and look at tour dates, it goes through November then a big break until April of 2027.
-If you google "treaty oak revival Birmingham", the first AI generated response that comes up says "Treaty Oak Revival is scheduled to perform live in Birmingham, AL on Saturday, December 26th at 7PM. The concert will take place at the Coca Cola Amphitheater". Then it says "Tickets Available via AXS" and provides a link. When I click on that link to go to the AXS site and then search for the band, it again jumps from November then next show in April 2027.
-Likewise for Ticketmaster, it goes from November to April.

Wtf is happening? All of the legitimate looking sources (the venue and the band) don't say a word about this date, so how would other sites like Stubhub or google just make that info up out of thin air?
