Training Effect missing on Edge1040, can’t calculate stamina

hi everyone,

so I’ve had this happen two times already - I complete an usual route with all the hr, power etc data logged correctly with over a year of consistent data, but garmin decides to give training effect as 0/5 and 0/5 with stamina staying at 100%.

first time it happened it was during just a ride, today I rode, turned in workout, did 50% of it, stopped the workout and then after a brief ride stopped the ride. can we get a fix on this? Or recalculate the effects? It has all the needed data so it should be able to recalculate the effects post-activity. I’ve seen this happening to some other people in the forum, but with no answer.
