In your first link there were several issues related to the ramps names, I've fixed them, so the instructions should be a lot clearer now.
Someone had but a "to: I-275 S" instead of "to I-275 S" (note the colon).

Your second example looks like a textbook example of the correct way to do it (Waze processes the next name in certain circumstances).
