[Plugin: bbPress Antispam]Cannot edit topics

I am using bbPress 2.0.2 (as plugin) and bbPress Antispam 2.0 on a network site. When both plugins are network activated, I cannot edit topics. When bbPress Antispam is deactivated, I can.

Steps I take:

1. Create a topic with some text in the Topic Description box.
2. Click on topic title to view it.
3. Click on the Edit link that is in the topic box.
4. Change the text within the Topic Description box.
5. Click Submit.

After these steps, the Now Editing form returns with no text in the Topic Description and above it, an error that says: “Your topic cannot be empty.” The topic description in the database has not changed.

I checked the page source after step 3 above and found this code to be the culprit:

<p>
	<label for="bbp_topic_content">Topic Description:</label><br />
		<textarea id="bbp_topic_content_css" tabindex="1112" name="bbp_topic_content" rows="6" cols="2"></textarea><textarea id="bbp_topic_content" tabindex="102" name="bbp_topic_content-46b80cea568a" cols="60" rows="6">test meta boxes today</textarea>
</p>

There is a textarea control within a textarea control. Turn off bbPress Antispam plugin and it works fine.
