Reply to Effects Select on FX Unit 1 with Shift modifier and Fader/Knob

I have an interesting problem that I am hoping someone might be able to give me some insight to.

I have a standard edition VCI-400 and I am slowly creating a mapping to emulate the EGE mapping. I have set my Effect 2 Select for FX Unit 1 to VR2 (or Ch 13.CC.002) with my shift (i.e. modifier) selected. When I set the Interaction Mode to Direct and adjust the knob it jumps to no Effect and I am unable to select any other effect. I have set up the other two effects in effects bank 1 and all of the effect in effects bank 2 the same way and they all work fine. I have found a work around by setting this particular knob to relative instead of direct, but I should not have to do this. Any thoughts??

Peace...
