Not monitoring webforms

I have noticed another issue seemingly identical to this but didn't want to necro it. I have the latest versions of both antispam and webforms modules installed. The webform node option is selected in antispam configuration, but no monitoring is occurring at all. I also have the "Show Publish/Unpublish Links" and "Show Submit Ham/Spam Links" options set but these do not appear either.

I'm not heavily technical, so it's quite possible I've simply missed a configuration step.

Thanks
