• Error when creating a Top-Level Parameter

    I'm using WESTforOPTIMIZATION 2017.
    I was trying to create a top-level parameter using the "A" factor of the aerator controllers (Empirical factor for che calculation of the alpha-SOTE). I first selected all the aerator blocks in the layout and then drag and drop to the Top-level Quantities window. But something went wrong... The "A" parameter is created but is no linked to anyone block and when I try to delete it it turns me an error: "System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary"
    How can I fix this?
    Thank you
