Editor issue : additional

Hello,

I am having an issue with the KNews editor.
My original WordPress article contains a table, here is the start of this code in TinyMCE:

<h2 align="left"><b>TITLE</b></h2>
<table width="75%" border="1" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td width="58"></td>
<td colspan="2" width="141">

When I select this post to create a new newsletter, here what is generated:

<h2 align="left"><b>TITLE</b></h2><br>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><table width="75%" border="1" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td width="58"></td>
<td colspan="2" width="141"><br>

How can I reduce the number of ‘
‘ produced?

Thanks in advance.
Regards
