New Nozzle for my flash forge adventurer 5m pro Need help

[JoseLRiveraCruz]

Hi, ive purchased a new nozzle for my flash forge adventurer 5m pro. Orca slicer currently has for this printer a 0.4 and a 0.6 option. when I go to create a new nozzle, first: flash forge is not under create printer/nozzle diagram, and if I click create nozzle for existing printer the option diagram does not allow me to do anything, it just shadows it and nothing comes up. If anyone knows how to fix this please. thanks!
