Missing DSP/filter Menu in Playback Options in version 2.246

Hi all,

I am running volumio in an rpi3 with a Pifi v2 HAT. I have just upgraded to the latest version, i.e. 2.246, and found that the menu to choose the DSP/filter for the HAT in the playback options is not there anymore. Is there anyway the menu can be accessed? Appreciate your help and advice. Thanks.
