I’ve seen this bug happen a couple of times, on different firmwares, but only under the following conditions:
1) An activity (ie a run) initiated with a Garmin Chest HRM connected, concluded and saved.
2) A second activity (ie a cooldown/Other activity) initiated a couple of minutes later but BEFORE the notification that HRM is connected.
3) Second activity concluded and watch prompts to download HR data from HRM.
4) Data downloaded and activity saved.
The bug: both activities are saved but only on the second activity is accounted for in Training Load. I can see both activities under Exercise Load but only the second activity’s Training Load appears in the total score. Is there a way to force the watch/app to recalculate or recount the training load? I’ve tried deleting the second activity, thinking it might be some sort of conflict between the two activities but it doesn’t change anything.
