A solution for some people will be to set their meditation goal to aggregate as max so that only one of those datapoints counts (the highest of them). That should work for those of you who only meditate once per day.
If you’re on the Bee Plus or a higher subscription plan you can do this yourself by changing the goal type to custom and then setting the aggregation method. (All on the goal’s settings tab.)
If you’re just frustrated and this duplicates bug* is standing in your way, email support and we’ll set that for you beehind the scenes.
* it’s unclear to me whether it’s something that we can do anything about, in the case of travel and timezones and how Apple Health is reporting those datapoints…
