Fenix 5 Plus - Not showing activity details

Hi everyone, today I ran a 10K and as always, I saved the activity on my watch and it showed me all the metrics of my run.
Later today I realized that the activity was not uploaded to garmin connect on my phone nor my computer with the watch connected and syncronized.

I checked the activity history on my watch and I can see the activity for the 10k but the watch doesn't show its details, only totals. Garmin connect doesn't show the activity, not even the totals.

I ran a 21k on Saturday with no problems. Did a quick session on Sunday with no problems also. Both activities are stored correctly on my watch with all their details, garming connect show them just fine. 

I had to input the activity on garmin connect manually, 

Any idea what happened ?

Thanks!!
