FFT Analyzer signal options unresponsive

Hello, I have been trying to use the FFT analyzer app in the powergui block form the simscape electrical add-on on my linux machine. When i try to modify the fundamental frequency or try to change which signal is selected, the window is just unresponsive. The analyzer works for the preselected signal and fundamental frequency but that's about the limit of what the app will let me do.
If it helps, I'm using the 2024b release.
The attached picture shows the options that I am unable to change.
