Can't change the underline in buttons

Hello, I am enjoying learning Xara Webdesigner and what I could accomplish so far. Now I ran into this problem when I was messing with soft groups and web properties and found out that the buttons Home and About Us have underlines, but contact us don't. I'm attaching the file to and some one can point out what happened. It is based on the theme "Legal"

Thanks,

Hi Eduardo,

Your Contact Us button has the text grouped with the button shape. Your other buttons do not have the text group. Ungroup the Contact Us button and the underline i shown.
