Adding text in Description of Activity always shows it as HTML coding

Hi there,
Since the upgrade everytime I add a new activity and use the bullet points or number points or any formatting, the Description changes to showing me all this HTML coding instead.

It only happens when I create a New Activity and SAVE the file.

Using 6.0.6

Copied direct from Database

<div><strong>REQUESTED BY GRAHAM</strong></div>

<div><strong>PROBLEM: </strong>Validating

<table style="height:100%; width:100%">
<tbody>
<tr style="height:35px;">
<td class="title" style="width:10%;">Activity<span>&nbsp;#770</span></td>
<td class="title" style="height:35px;">
<div style="width:100%;height:100%;position:relative;">
<div style="width:100%;position:absolute;top:8px;text-overflow:ellipsis;overflow:hidden;">&nbsp;-&nbsp;Unable to save Store Settings &gt; TAB: Share because Field requ</div>
</div>
</td>
</tr>
</tbody>
</table>

<div>I find two errors.</div>

<ol>
<li>Google Chrome not display Product Description properly for Customer FrontEnd</li>
<li>Store Settings Menu &gt; Share TAB = when press checkbox and save.&nbsp; System Say Updated Setting but still problems
<ol>
<li>it not save settings for Shared when do checkboxes</li>
<li>it not display correctly on Customer Front End for settings share save.</li>
</ol>
</li>
</ol>
</div>
