Hi Scott,
As schematics weren't able to copy over to a new file, I drew a fresh file from scratch, attached. The same issues occurred in a blank file, as shown on the unit channeled 2. I also included a different bug in where if you over-rig a fixture, the schematic can't line up the channel number and container. In this symbol in particular, it also appears to mess up the symbol within a symbol and split some line work in the plan view.
