nRF51822 pin 21 and pin 22 strange behavior

Hello,

I'm using a nRF51 DK and nRF51822 with costum board. Im using BLE_API obviously. I have LEDs on pin 21 to pin 25 and a led on P0_22 is ON constantly, but with lower brightnes (dimmed). I checked my code 10 times and its ok. I cant post my code because Im using it for a comertial product. Also P0_21 LED lights up when connecting, but thats ok, we called it a feature.

In the manual P0_22 is a normal Digital I/O.

Thanks!
