The editor is adding the background style on some modules or portions of text.
My users need to go into each module and edit out the added style references with each edit.
Sample below......
<div><font style="BACKGROUND-COLOR: #cccccc">How can my organization participate in the program?</font>
</div>
<ul>
<li>Simply complete the registration form and someone will contact you.</li>
</ul>
This happens without the list as well.
