Comment Syntax Incorrect in 2.1

I saw this on JRoller when they upgraded to a rc of 2.1...

I just upgraded raibledesigns.com to 2.1 and my comments now say HTML
Syntax is *Off* even though it's *On*.  I see the same problem at
JRoller, except it says it's On when it's Off. Doing a view-source
shows a missing class it seems:

<span style="">
            HTML Syntax:
                            <span class="enabled">Off</span>
                        </span>

Any ideas how to fix this?
