FitContributor MESG_TYPE_LAP values don't appear in the Garmin Connect activity record

I have a data field that writes FitContributor  MESG_TYPE_LAP values.

I call FitContributor.Field.setData(..)  within onTimerLap() but when I look at the saved activity record in Garmin Connect Mobile or the web version, I don't see any of my values saved.

The data field was attached to a run activity and I ran a distance tha recorded multiple laps (km).

I downloaded the FIT file and converted to CSV and could not find  my lap values written there. 

Are FitContributor lap values just not visible in Garmin Connect at all?    If they are , where?

Does the :nativeNum option have anything to do with this?
