By using a work-around for the actual filepath for UPP, everything loads as expected and my options are not greyed out after selecting the card in the dropdow.
I used git clone https://github.com/azeam/powerupp.git & just ran powerupp.desktop from the generated folder & it's now working for me again. Thanks! :)
