Figured out that the issue still persists even after cleaning but now only on 1 knob which is the Level and not the others.
Checked with all other individual knobs with my above steps and everything seem to be working fine now with them(before cleaning they were not working as expected)
Hopefully one more round of cleaning shud resolve the Level knob problem as well..
