Upgraded from something pre new form builder stuff to 5.49.3. Now in Mosaico the top block, header, looks fine in the drag and drop stuff but when you view it in html, instead of just see the the unsubscribe and the view in your browser at the top you also see the full mailing address and civicrm/mailing/optout?reset=1&jid=&qid=&h=fakehash above the links.
I've tried to create a new template, same thing.
In the generating HTML to either email or to just view, it's adding in the organization snail mail address from admin organization address and contact info. (I tried changing that info just to verify that's where it's coming from).
