ADAU1701 pushbutton doesn't work with debouncer on

We use 2 momentary push-button input in active-high configuration to control the volume. These 2 circuits are identical and connected to MP7 and MP8 GPIO pins.

With the debouncer ON the button on MP8 doesn't work, MP7 works fine. The button on MP8 only works when the debouncer is set OFF.

 

Why it doesn't work?

 

This is the hardware configuration.
