Proximity Sensor is mocked to 5cm, screen still goes dark

After replacing the display of my Xiaomi Mi A2 Lite, my proximity sensor is giving me wrong values (saying, my phone is always covered).
I mocked my sensors using the XPosed Sensor Disable App, and the various sensor test apps tell me, that the distance is 5cm (the maximum). Still, my phone's screen goes black when playing audios or making a call. Am I missing something? Maybe another sensor's setting?

The way I mocked my Sensors was the following:

LTR579 ALSPS: 5cm, LTR579 ALSPS-Non Wakeup Secondary: 0cm

I'm really out of ideas, it would be great if someone could help me! I'd hate having to open my phone again, and I'll happily do without the screen going black feature. I honestly have no idea why the test says "5cm", but the phone still decides to go dark. >:(

Thanks alot for any ideas!
