Link Pi ENC1Pro audio issue

I received my enc1pro a week ago and have been playing around with the encoding settings but for some reason the audio encoding seems stuck at 32kbps. I have updated the enc1pro firmware to the latest version:
App version
4.1.0 build 20250430_2733
SDK version
4.1.3 build 20250430_29968
Sys version
4.1.3 build 20250430

Unfortunately, the issue seems to persist. Please could you help. Please see the screenshots below of the current encoding settings

Any help appreciated

Thank you
