Hi Jason,
It turns out that this is a limitation of Open Source Scalr that has been changed in the latest release of Enterprise Scalr. This is why the reset is not working for your admin user as expected. As a workaround for this, you can execute the following:
UPDATE account_users SET password='8c6976e5b5410415bde908bd4dee15dfb167a9c873fc4bb8a81f6f2ab448a918' WHERE email='admin';
This will reset the admin password to the specified SHA256 hash. In this case, the above hash represents a password of "admin".
Before executing this command, you will want to change the SHA256 password hash value to something unique and secure. Let us know if this does the trick for you.
Cheers,
