It looks like you may not have enough public watch hours to be eligible for review. Creator Studio shows public & private combined, but you need 4k public hours alone. Try switching private videos to public. More info here: https://yt.be/help/YPP-review
Wait... what? What in the heck is "Private Watch Hours"? This here sounds like a glitch in your system. Especially when all of those videos are public. What does that mean for me then when I get to that point? Since all my videos are public too... Something sounds wrong here.
