It's only components that can be "1-" and this is controlled by typing the text "1-" into the WDTYPE attribute of that symbol.
THe black name has nothing to do with it. This also means that there's wire types that are "one line". Aires are wires. It all depends on what components they are connected to.
If you run a from/to report for category "One-Line", you get all wires connected to One-Line components.
For the rest of your question it would be nice to see a screenshot or two, showing the problem(s).
