List item not ordered well

I like newswire theme but to the fact that it has some bug I think in the list item. I created an article at http://www.sourcecodester.com/tutorials/net/database-programming-made-ea... that has a sub item like:

1. Making Database Connection
2. How to Retrieve Data

   1. Using Data Reader
   2. Using Datasets and Data Adapters

3. How to Modify Data

   1. Using ExecuteNonQuery
   2. Using Datasets and Data Adapters

4. Windows Forms

   1. How to Retrieve and Save Data using TextBox Control
         1. Using Data Readers and ExecuteNonQuery
         2. Using Datasets and Data Adapters

This should follow the correct format like:

1. Making Database Connection
2. How to Retrieve Data

   a. Using Data Reader
   b. Using Datasets and Data Adapters

3. How to Modify Data

   a. Using ExecuteNonQuery
   b. Using Datasets and Data Adapters

4. Windows Forms

   a. How to Retrieve and Save Data using TextBox Control
         i. Using Data Readers and ExecuteNonQuery
         ii. Using Datasets and Data Adapters

Anyone know where to fix this?
