Are there repeated nodes in "Refinery Toolkits" package?

Hi everyone.

I would appreciate your help. I was reviewing the “Refinery Toolkits” package and in the Space Planning section y found different nodes repeated. I’d like to know if there is a difference between them or maybe it was an installation problem.

Looks like an installation problem, perhaps from installing a new version atop the old via the previously separate pack add Es which were combined.
