non-updating fitness challenges

Using an iPhone 14pro and an apple watch 6, both OS up to date, i have found that some of my Apple fitness challenges are not registering / updating.

I close my rings, and am getting monthly move goals, perfect weeks, 7 work out weeks, monthly challenges, and such like. But i have noticed that the progress towards my 2000 move goals has been stuck on 1931 for a very long time (at least several weeks). I also went away recently and did a lot of swimming, and recorded 7 swimming workouts in 3 days, but have not received a 'longest swim' badge (for having completed at least 5).

I have restarted both devices several times since i started noticing this behaviour, and been through several updates.
