Exact steps for others to reproduce the error
Open the geometry Node Editor.
Duplicate the group output node, Subdivision Surface will invalid.

This is a design question that would require a decision by the module team how this is intended to work.

Geometry nodes don't seem to follow the same concept as material nodes as there apparently should only ever be one group output. There also isn't an entry to add additional group outputs in the Add menu, but duplicating an existing node of that type works. Perhaps the copying & pasting and duplicating of the node should be prevented to be consistent in that only ever one is allowed or there needs to be a concept of an active output similar to the material nodes.

Thank you for your reply.
One group output will be fine. In the shader editor, I like to use this method to check different parts of complex nodes. Emm... I have to say it is very useful :)

Will confirm for now, agree one of the two should be implemented:

copying & pasting and duplicating of the node should be prevented to be consistent in that only ever one is allowed or there needs to be a concept of an active output similar to the material nodes.

Thanks for the report, but this is a not a bug. The system is working as it was designed to. It works the same way any other Node Group in Blender, including the ones used in material.
