I can patch a Led8 fixture correctly and fixture icon are selectable. Then I add 2 RGB fixtures and Led8 fixture icon are automatically disabled. Unable to select Led8 fixture. I tried to close / restart the software but it causes another problem, all Led8 palettes disappears except color.
For now, I can't find out how to use this soft with my fixtures

Any workaround for this ? Is this a known issue ?
