This happened after installing 19.20
Done a 10km run with my new p.b on 1km, 1mi and 10km, prompted on the watch.
But after saving the activity only the 10km p.b. was recorded, not the others (on the watch and on garmin connect page/app)
Same thing yesterday: new p.b. on 1km, 1mi and 5km on a 5km run. Only the 5km p.b. was recorded
