How do I suppress unwanted markup in the HTML tab of the Edit Content box on the Admin page? 

1.     I input the following:

<h4><a name="Accounting &amp; Tax Services for individuals/businesses" target="blank" re_target="blank"></a>ACCOUNTING &amp; TAX SERVICES FOR INDIVIDUALS/BUSINESSES</h4>
<ul>
    <li>Tina M. Mattis, CPA<br>
   
    1536 W. 25th St., Suite H, San Pedro, Ca., 90732<br>
   
    310-498-1965 <br>
   
    Website: <a href="http://www.tinamattiscpa.com" target="_blank" re_target="_blank">www.tinamattiscpa.com</a> </li>
</ul>

2.     I click on the Design tab and get this, which is what I want:

ACCOUNTING & TAX SERVICES FOR INDIVIDUALS/BUSINESSES

• Tina M. Mattis, CPA
  1536 W. 25th St., Suite H, San Pedro, Ca., 90732
  310-498-1965
  Website: www.tinamattiscpa.com

3.     I click on the HTML tab again and get additional </br>'s:

<h4><a name="Accounting &amp; Tax Services for individuals/businesses" target="blank" re_target="blank"></a>ACCOUNTING &amp; TAX SERVICES FOR INDIVIDUALS/BUSINESSES</h4>
<ul>
    <li>Tina M. Mattis, CPA<br>
    </br>
    1536 W. 25th St., Suite H, San Pedro, Ca., 90732<br>
    </br>
    310-498-1965 <br>
    </br>
    Website: <a href="http://www.tinamattiscpa.com" target="_blank" re_target="_blank">www.tinamattiscpa.com</a> </li>
</ul>

4.     Again on the Design tab (this is what shows up when I exit Edit Content):

ACCOUNTING & TAX SERVICES FOR INDIVIDUALS/BUSINESSES

• Tina M. Mattis, CPA
  
  1536 W. 25th St., Suite H, San Pedro, Ca., 90732
  
  310-498-1965
  
  Website: www.tinamattiscpa.com

PLEASE TELL ME WHY I GET THE ADDITIONAL MARKUP.

THANKS!
