Correcting miscalculated achievements?

I’m a bit confused as to what is happening with the calculation of Achievements on my fitness chart. When I look at the season view going back a few years with Achievements turned on, it shows ‘achievements’ for nearly every ride, almost all of which are seemingly completely random. The chart in full:

and an example of one such ride when hovered over:

I’m not sure what is happening such that the analysis sees these things as achievements when they are well below the power I’ve done for efforts in the same timeframe. Is there a setting that needs to be fixed in those workouts to recalculate achievements? After some point around January 2024, it seems to have corrected itself.

What seasons do you have defined in your settings?

The only defined season is the same as an effective ‘all time’ slice. it starts january 2019 and does not have a defined end date.
