[Activity App] Monthly Challenge differs between iPhone and Apple Watch

I've searched the internet and can't find anyone talking about this particular problem.

Regarding the Activity App and it's Monthly Challenge program. For December 2023, my Apple Watch and iPhone (which are linked and otherwise correctly syncing my progress for rings and other metrics) have completely different challenge conditions.

My Apple Watch wants me to "Burn at least XXX Calories per day 14 times."

My iPhone wants me to "Close all 3 Activity rings 28 times this month."

Furthermore, I have actually completed the challenge on my Apple Watch for the month and the award appears to have been earned. But it has not been earned on my iPhone.

Something that may well be related is that I upgraded to a new iPhone at the beginning of this month and paired my watch to the new phone. The old iPhone was using iOS 16.7.2. I moved to the new iPhone by restoring an encrypted backup. The new iPhone was initially on iOS 17.1.2 and now upgraded to 17.2. The watch I'm not sure which watchOS it was running, but probably the latest as of the beginning of December. Just upgraded it to watchOS 10.2 yesterday.

Anyone else experienced this issue or saw it talked about? Do you think next month's challenge will work correctly and it is just a discrepancy related to pairing my watch to a new iPhone?
