QRadioButton fires slot twice

I have a form created in PyQt5 Designer. This form has a QRadioButton on it. When the button is clicked some code runs and a function is called. The function creates a stackedWidget and loads some labels and sets their text. The code is creating two stackedWidgets but only the top one is controlled by the list that changes the pages. At first I thought that it was a code problem but it turns out that the QRadioButton is firing twice. The function call was only added recently, before that, the code that ran had no visual que and it didn't matter that it ran twice. I can't believe that I am the only one to ever have this problem. Does this only happen on my computer?

Which signal are you connecting to?

Cheers,

I tried all of them, but it turns out that it is just my computer. I loaded it on to another one and have no problem. Weird.
