T-series brakes lock up at >25% pedal input

Hi everyone,

For some reason, when I depress my brake pedal more than 25%, the brakes on the T-series lock up (every configuration). 25% is literally feathering the brake for me, it's waaay too sensitive. This doesn't happen with any other vehicle. I don't have much knowledge of trucks, so I apologize in advance if it's a stupid question, because I don't know if it's a bug or if I'm missing out on something. I already have a slight curve on my brake pedal in settings. This "bug" makes it really annoying to drive trucks, which is a pity because trucks seem fun to use.
