It's easy to accidently try to edit the upstream or downstream OCP settings by using the Edit Family tools on the detail item instead of the electrical equipment or electrical fixture. It even lets you go so far as to fill out the settings for the detail item, but you won't see the results in your model. It would be nice if there was a warning if you try to use the Edit Family tool from within a Detail Item, since that likely means you're editing the wrong information.
