No strokes statistics for open water swimming

Hi, I'm a relatively new Garmin user. I've been to open water twice this year and both activities lack strokes statistics. In both cases, I see the statistics that I made 0 moves, which is obviously impossible when swimming freestyle.

The problem occurred on two stable versions of the software: 17.20 and 17.23.

Interestingly, for swimming in the pool, the watch has no problems detecting the number of strokes, so it is not a problem with the accelerometer or gyroscope.

Do you also have this problem? Did you manage to solve it?
