It’s set in manager/includes/header.inc.php.
It’s used in the function getTVDisplayFormat().

No need to worry about that. I think it has to do with the cache and left overs from a manager sessions. It will show if you are logged in as manager (i think it will show if anyone is logged in as manager, not necessarily you, but I am not sure), but if no one is logged in and the cache cleared then it should not show (but sometimes still does).
I have seen this mentioned a few times in the forum but don’t recall a solution for getting rid of it.
