Panning Bleed and Selector

Hi everyone,
I'm a beginner at Max/MSP. I combined (I think it was) B.K. Shepard's panning patch from some forum post(see attachement), with a slider and a wet/dry dial with these mixing patches I found somewhere else (don't remember the source). I wondered if anyone could give me feedback about the following:

1) Why is the signal bleeding between left and right when the panning W/D is on 100% Wet? (when checking the outputs from the pan2 object, the left and right output appear to be properly connected to the left and right on the slider)

2) I'd like to add a selector patch to be able to switch between the different waveshapes, but after lots of searching I just can't get a selector patch to work yet (see attached file on the right). What am I doing wrong?

I'd be thankful for any tips!
