The Lighting Controller

I deleted a fixture in Fixture setting and then deleted the two fixtures in DMX addressing. I then Created a new Fixture in fixture setting and added a fixture in DMX addressing. I am trying to reuse some of the channels i just freed up. The new fixture will not show up in the editor. Is this a known bug or can I not do this? There are no scenes for the old fixture in the file. i have run into this problem in another show. How do I get this to work or is there a work around for this?

It is working now for some reason the fixture name was saved with no channel definitions and the channel definitions were in a differend file with no name. I'm not sure how that happened. Anyway it works now. Sorry!!!
