Why watch time different in Youtube Analytics and Monetization page?

Recently my Youtube channel crossed 4k hour watch time in the last 365 days. I have 1301 subscribers and 4.4k hour watch time. Please see the attached image.

So, as per Youtube rules I can apply for monetization now. But in the monetization page, the subscriber count is 1290 and watch time is just 1661 hour. Why?

I waited 2 days thinking that it may take some time to update their databases, but nothing has changed. Why is there such a difference in Analytics and Monetization pages?
