(Re: SU/Vray 20. plugin) I had that issue with lights inside components once before and a restart of SU fixed it for me that time. I just had it happen again in a different model and here's another thing I just tried that worked for me & is quicker: EXPLODE one of the components, pick the light and go to edit that individual light. You should be able to get to the edit box now, but don't, now just deselect and UNDO the EXPLODE and you should be back in shape!
