When moving props in the visualizer from one port to another, there is a fantom assignment of a prop left onto the old port.

We were adjusting our props, and had 3 sections of icecicles chained together. We moved all 3 props to a different chanel per prop. All were on port 4, now 1 is on 8, 2 is on 9 and 3 is on 10. when we open the falcon f16 v4 /w 2 expansion boards, it reports 1 is assigned to port 4 and also on port 8. port 4 showing 0 pixels, and port 8 showing 70 pixels. (70 is the proper count). We are unable to use port 4 as it will not assign a different prop to that channel any longer. We are using most of all of the 48 ports, up to about 40 ports. is this a buffer overrload?
