fitContributions and no units - blank dataLabel

Hi,

I am trying to record a value using FitContributor. All works a well, but it's has no units, or not ones I want to define (it could be Goals in Soccer, Tries in Rugby etc).

Anyway, when I set the dataLabel value on fitContributions to empty, Connect adds a nice long GUID after the number when displaying the activity. I've temporally added a dot (.) to stop this. However is it possible to not set any units?

Thanks
Chris
