Spell Check Document Corruption

Spell Check Document Corruption

I've started experiencing a problem whenever I attempt to spell check a document. For some reason it exposes some html code that I have to manually delete. Any thoughts on what is happening or how else to correct it?

Here is a sample:

Jurisdiction types and prices are:
<td style="vertical-align: top;" ztagid="78">$18.00 >>> <!--</span-->tr> d style="vertical-align: top;" ztagid="102">N/A
d style="vertical-align: top;" ztagid="110">N/A
