Auto Lap Issue in Pool Swimming: Last Lap Merges with Previous Lap on Fenix 7

Hi everyone,

I’ve recently been experiencing an issue with Auto Lap while pool swimming using my Garmin Fenix 7.

What happens:

  • For example, if I swim a 1000m session, the watch correctly shows 1000m when I finish.

  • Then I stop for a few seconds to drink water at the pool wall.

  • After a short pause, the total distance automatically drops back to 980m — the last lap seems to disappear.

  • When I check the details on Garmin Connect later, I see that the last lap was (maybe) merged into the previous lap. So instead of having two separate laps (e.g., Lap 49 = 20m, Lap 50 = 20m), the previous lap shows a double time.

  • The final distance still shows missing meters because of this merge.

Details:

  • Device: Garmin Fenix 7

  • Sport Mode: Pool Swimming

  • Pool Length: 20m

  • Auto Lap: Enabled (default)

  • Firmware Version: 21.19


I didn't encounter this situation before.

Now I fix my mistake by manually pressing pause at the end of a set.

I would appreciate any advice or insight from other swimmers or Garmin staff.

Thanks a lot in advance!
