I've found a clue. It reports IPS and Download Protection contents as outdated. If I set them as warn after 900 days, it's green again.
The problem is, both are not such outdated, but still show them as outdated. I think it has something to do with the date format.
Now, I've set regional settings to m/d/y, but the console still shows d/m/y in some screens. So I think it can be miscalculating with
dates, and thus it warns incorrectly.
But I don't know how to fix it !
