This is what I have figured out:
1. Go to Homa Tab, Styles group.
2. Click the arrw at the bottom right corner of the Styles group.
3. When the dialogue box opens, go to tthe bottom and click "Manage Styles"
on the bottom right.
4. When the next dialogue box opens up, click "import/Export" at the bottom
5. When the next dialogue box opens, you will see to fields. The name on the
right side is "In Normal."
6. Under the In Normail field, highlight the style that you want to delete
and click delete.
7. Click close. Thats it.
