Mixing Console - Agent Filter

i use C7 mainly to produce songs with vsti’s. My approach is to load any vsti in the instrument rack (single or multi channel) and create midi channels to control the vsti’s. I don’t create instrument tracks cause then its a bit to tricky to sort the tracks in the way i want them to be show in the mixer. So the order of the appearance of the tracks is depended on the order of sorting the vsti tracks. That works for me.

Now to the problem/question. I got plenty of channels in the mixing console (vsti channels) which i want to filter with the agent function. No matter what i choose i.e. just channels with data or channels with data between locators all channels disappear. Does the filter just recognize audio data ? Please help or confirmation of a bug.

Nobody an answer ?
