Got it now, I had the override made but had forgotten to save and reload the file. After doing that I have all the options again, guess I forgot that step! Thank you for the help troubleshooting 🙂
Thank you for the reply, though I have done that in the CGC_VonnBots_4.0.2.blend file the issue is still occurring with Rivet when he is linked into a new Blender Project for me.
