All new 'statuses' considered 'Registered'

First -- great module, thanks.

I have added a couple of new Sign Up Statuses on the Admin page. However, in the roster of sign ups for a particular event, under 'Sign Up Summary,' there is the following wording:
"The following statuses are considered to be Registered (Will Attend): Registered (Will Attend), Might Attend."

Obviously, I would not want the organizer of an Event to think that 'Might Attend' = 'Will Attend'. I do not see how to get rid of (or control) that wording on the Admin page. I don't think it triggers any actions, but I would like to get rid of it or have it function correctly.
