Swimming Activity will NOT sync to Garmin Connect

HI folks, I have a Fenix 6S Saphire, I had it for 1 year now.  I am on release 9.0.0.0.

Yesterday I did a pool swim activity, which I saved as I normally do.

This activity does not sync to Garmin Connect.  I can see it on the watch, but no matter how many times I sync-hed the watch the acitity does not show on Garmin Connect.  This is the first time this happens/ 

Any ideas why this is happenning.  How can I get the  activity to sync?
