Error linking Heat Transfer in Fluids and Turbulent Flow (Spalart-Allmaras)

I am using COMSOL Class Kit 4.1 to model a pretty simple flow of hot air in a vertical pipe. I was able to get the model to working using Laminar flow (all are steady state studies) and the Heat Transfer in Liquids physics, but I get this error in trying to get the turbulent physics to work: Constraint found for variables in different Segregated groups. Try to merge these groups.

I disabled the Laminar Physics before adding the Turbulent module and I am using separate studies under the same model.

How do I merge the constraints or other wise troubleshoot this error???

Thank You.
