Not sure what's going on here--I'll look into it closer. But one idea may be to use the Space function in a calculated field. Hope this helps!
Thanks for the response Tracy. I have tried using a calculated field - no luck. In case it helps, here's a sample of what I'm talking about. Before publishing:
It looks to me like Central East and South are maybe one space over from West, but certainly not indented to the degree that would make a hierarchy clear.
