Charging over 80% with Optimized charging

My 6 months old Macbook Air M3 is always charging to 100% even though my Optimized battery charging is on all the time.

And it goes really fast over 80%, it just doesn't slow down.

I know it should have learned my charging routine but it always overrides the one rule that is supposed to follow: not to charge over 80%.

Why is that? Does anyone else have this problem?
