Multiple instances of the same parameter value showing in dropdown

I checked my parameters in revit and there is no project parameter that is called structural. I know that it is possible to have parameters with the same name, since the unique identifier is an int that serves as a primatry key not the name string value. Built in parameters should only have one value?

Yes, the parameters can have the same Name, in the searchable built in parameter picker there is additional info that is helpful

Super helpfull. Thanks. Will use the parameter picker then. It would be great to show that information in the drop down as well since its a bit confusing to see multiple names without more context.
