Another thing that can effect this is the "Power" control on the "Multiband" page of Audio Processing. The lower it is from Infinity:1, the less change there will be between the input and output of the multiband. Set on 2:1 there will only be a 50% change from the input audio, to what the output can be. This is intentional on a number of presets, and is part of their sound, but please do play with that setting also, to see how it effects the sound (and you may notice the processing meters changing too)
