Troubleshooting • e-Paper 8PIN works but HAT does not

I bought a Waveshare e-Paper [1] display and the sample programs work fine with 8PIN connecting method using the GPIO pinout diagram [2] but HAT connection method doesn't work. Running the sample program shows nothing on the display nor on the terminal any errors. The error persists on Model 2B and Zero WH and two different Waveshare displays. I have masters in computer science so anything software related I can handle. I have no experience whatsoever in electical engineering though so I'm quite lost here.

How should I start troubleshooting this?
