Login button on jomsocial popup missing?

The jomsocial login button is not working when you are not logged in. I am referring to the popup window that the user gets if they click on "add a friend" or "message" when not logged into the website. They receive the popup but the login button on this popup is missing as you can see from the screen?

Ok this bug here is definitely a deal breaker for me - this means not logged in users have a hard time logging in - a critical bug in my opinion on such a community website.

Shameless bump here again - this is a big one in my book as its more than just styling its the actual login to the site and half the button is missing! Any chance of a fix - the new release does not have one
