Seeking help: an error occurs when attempting to calculate the Murphree efficiency for a single component in Aspen

Dear fellow users, an error appears in the control panel when entering the Murphree efficiency value for the components – what’s going on? *** SEVERE ERROR WHILE CHECKING INPUT SPECIFICATIONS: BLOCK NAME T1201, MODEL NAME RADFRAC MURPHREE. THE EFFICIENCY PARAMETER CANNOT BE USED WITH THE TRUE SPECIES APPROACH FOR ELECTROLYTIC COLUMNS WHEN GIBBS FREE ENERGY IS USED TO CALCULATE THE EXTENT OF REACTIONS.
This error message indicates that when using Aspen for simulation, you are attempting to set a Murphree efficiency for an electrolyte column, but this setting conflicts with the True Species Approach that you are currently using. In an electrolyte cell, when Gibbs Free Energy is used to calculate the extent of reaction, the Murphy efficiency cannot be applied. You may need to change the separation method or adjust the model settings to avoid such errors. You can consider using other methods for defining efficiency, or check whether there are other feasible simulation options, such as simulations that do not take into account the effects of electrolytes. .
Thank you so much; using the vaporization efficiency avoids errors and the simulation results are also very accurate.
