read a parameter after updating it in another class

[MKS2020]

Hello, I am using the managedwindow to live plot IV from a keithley2420 using the pymeasure module. It works but for some reason i cannot read a parameter defined in the first class that is updated in the queue function. here i define a parameter mode that takes the nature of the measurement 2 or 4 wires. when i queue experiments i can change that parameter in the GUI and record a new set of data. i can check in the keithley that the 4w mode is on and in the data file i do see the right mode parameter. i am trying to get that parameter as a string for my filename so i typed in str(self.mode), but the mode is stuck to the default value defined in the parameter, it is not updated after typing in the new value in the GUI whereas the right data appears in the file?. I did inherit the second class from the first. i use fake data to test the code below.
