ILS Approaches Class GPS Nav

Taking the ILS approach “test”. I’ve watched the training video numerous times, and I seem to be stuck. After I’ve set up the nav radio to 110.30, set the loc 1 to 320, I set up the procedure with Texen. And then I go to the CDI soft button and switch to GPS. But if you look at the screenshot below, it shows going direc to MODEP faf?
I am clearly flying away from the airport. And when I turn off autopilot and manually fly to the airport, I don’t get a glide slope indicator.

What am I doing wrong?
