Toolboard: 4028 Fan wired correctly but behaving inverted.

Basically the title.

Ive tried all manners of trying to the the pin to invert in klipper and nothing seams to be working.

Here is the config section:
[fan] pin: !toolboard:fan_part_cooling_pin tachometer_pin: ^toolboard:PB8 tachometer_poll_interval: 0.0005 enable_pin: PA2 shutdown_speed: 0.0 cycle_time: 0.00004

One weird thing is that even if I put a random port on the pin line. The fan still is controllable with the slider but just inverted. Even if I delete the whole line, nothing changes.

The behavior is as follows.

0% = Fan off
1% = 100 fan
50% = 50%
85% = 0%
