P/A Factor 7900 ICP MS MassHunter

Hello, I have the new MassHunter. Well, my P/A factor has failed. :-( do I correct this?  I don't understand how to correct it. I am supposed to select a measurement from the "Load Mass List from Method". and added it. Unfortunately, the Current Value is not available. What did I do wrong? What do I need to do now? Thanks in advance.
