Extruder unloads filament after filament sensor gets triggered

So, I just got my MK3S+ kit a couple of days ago, after I built it, fixed a couple of issues and flashed the firmware, I am now stuck.

The problem occurs when the filament sensor gets activated because for some reason the extruder just retracts the filament and this continues until you stop the filament load.

I also checked if the sensors return the correct values. 

 

Best Answer by cwbullet:

I would loosen the screw that mounts the sensor.

What happens if you temporarily disable the sensor (LCD menu)?

Thanks for your advice! But the screw is as much loosened as possible.

IMHO this is the same problem as here, see the solution that worked for me there. I'm not fully convinced that this will be solved by screw tension alone.
