Hello Wesley Upchurch !

The logo setting has been bound to the non-existing record in the sys_images_custom table. If you meet this trouble with the "unremovable" logo you may drop it with the following MySQL query:

UPDATE `sys_options` SET `value` = '0' WHERE `name` = 'sys_site_logo' LIMIT 1;

and then clear the cache via the Studio->Dashboard->Cache area.
