SubSystem block does not have a parameter named 'ST'

Hello I am trying to simulate a transformer for HV and LV failures. I am using the Multi-Winding transformer block from Simscape-Power systems on Matlab R2016A. Nevertheless Every time I try to switch from a saturable model to a linear one I get this error message:

SubSystem block does not have a parameter named 'ST' Component: Simulink | Category: Model error SubSystem block does not have a parameter named 'Ts' Component: Simulink | Category: Model error SubSystem block does not have a parameter named 'InitialFlux' Component: Simulink | Category: Model error

When looked for the initial flux pane on the transformer dialog box I realized that I can not update this value on the transformer pane. If I switch back to saturable transformer the system works fine again. Has anyone faced this before?

Regards!
