Alphabetical Listing Problem

I've seen others with the same issue, but none of the fixes have seemed to make a difference on my site. Anyhow, I have an alphabetical view on the page ( http://www.yinyanghouse.com/theory/herbalmedicine/tcm_herbal_medicine_da... ) sorted by the node title. I get multiple letters "X" for examples shows up twice with (1) node but they both contain both "X" nodes.

* B (1)
* D (1)
* M (1)
* S (1)
* X (1)
* X (1)
* Y (1)
* Z (1)

From the "X" page:
*
Xi Jiao (Rhinoceros Horn)
*
Xuan Shen (Ningpo Figwort Root)

I don't know if this is a problem with views, or just my code. I've included the view itself below and would greatly appreciate any help in making this work correctly.

Here is the view:

  $view = new stdClass();
  $view->name = 'tcm_herbal_medicine_database';
