I edited a previously created fixture via the fixture editor to include ranges, clicked "Save" (save confirmed). The new range-names will not display on the slider. I tried to re-patch the fixture, but the "Patched" window will not let me delete the existing fixture! Other fixtures in the list, including custom ones, I can delete. What's going on here?

Is it possible that the fixture is programmed in a cue?
As long as the fixture is used in a cue, you cannot delete it from the show.
