It's fine
Short nitpicking feature of am redemptions

If your redemption is waitlist, your deadline is stated in mmb as 17:00 hkt

If the redemption is sent for ticketing, your deadline is stated as 00:00 hkt

This translates to 14:00 and 21:00 respectively

So your upgrade definitely has been sent over to ticketing to process - you won't lose the seat

However I'd still follow it up after a couple of weeks cos they may do stupid things like take your credit card info wrong. Or in the case of upgrade, your revenue booking details perhaps?
