On the "Install an AppExchange dashboard package and make updates to one of the dashboards" challenge, I do not have the option to change the wedges to Lead source.... Only prospect source. Has anyone else encountered this issue? 

reference error id: DPFVJULB 

All modules (before and after this one) verify fine!  The flow works perfectly.  However, this one will not verify...I get an error that tells me to try it in a new DE.  I hate to start over and get the same issue when everything around it works fine.  Is it just me?
