ADAU1701 external volume problem

I have a problem with the ADAU1701 and SigmaStudio using the Single Slew External Volume with external potentiometer to control volume.

Using this block the DC offset voltage of the DAC changes from 1,5V (volume at minimum) to 1,8V (volume at maximum). 1.8V is the "standard" offset voltage without using this block in the audio chain.

Why is this happening?
