Failed Supercharger session shows same charge cost as successfull

I tried to use a Tesla Supercharger but it errored out (red).  I then went to an adjacent stall and charged successfully.  TeslaFi is showing both the failed charge and the successful one with the same charge cost (matched to invoice).  So now the stats show double the cost for the day. 

I don't want to delete the charge attempt as want to keep it in my history.   How do I change the cost to zero?
