Hello,
I’m having problems with containers and I need to understand what is doing Rhino in this case. I’m running Rhino 8 in Mac with the attached containers.xml, and for unknown reason it’s duplicating my container in Windows → Containers menu as you can see in the picture. How is built the options in the Containers submenu? What are the sources?
It shouldn’t be possible to have two containers with the same name and I’m so far not able to replicate this issue. Can you click on Manage Containers at the bottom of that list and then Export the container before deleting it from the list? If you see two entries of the same name, delete both. Then close the manage containers dialog and see if the list shown in the menu is fixed. Manage the containers again to import the rhc file you exported to get the container back and hopefully only once. Any luck?
