I guess it is an issue with the Additional Dataset which is downloaded seperatly. Go System Settings -> Unistall Programm -> Revit Architecture
then a diagolgue appears asking you if you want to repair the Program or add additional Functionality. Choose Additional Functionality and choose The Template Package you want to Download and the Package which you want to set as main Package.
I hope that helps
