Swim activity not sync


today my swim is not showing in Garmin Connect. On the watch it's there but also missing the bpm data. I was wearing the HRM-Swim and it was connected.
I tried to open the activity on the watch and sync my chest strap, but there is no option. HRM-Swim is connected to the watch.

Any ideas how I can fix it? When trying to download the fit file directly from the watch it's incompatible to Strava. http://www.swimmingwatchtools.com/ is showing the data from the fit file. But of course my heart rate is missing.
