If I change the accessory to none as you suggest. Both the accessory and the light change to none. With past versions of VW I was able to give each device its own legend. Now it is either they have none or both have the same legend.
When I add an accessory to a lighting instrument in Vectorworks 2021 Spotlight it creates a second legend that matches the lighting instrument. If I try to change the accessory legend to a different legend Vectorworks changes the legend on the lighting instrument to the new legend. I cannot use two different legends for the light and the accessory. I am using Vectorworks 2021 SP4.1 (Build 610975) and a MacBook Pro running OS 11.6.
