Hi Kathy. I just took a look at your link using Firebug/Firefox. The first thing I noticed was an error: ReferenceError: O is not defined, it points to http://maps.gstatic.com/maps-api-v3/api/js/20/8/main.js line 375 > eval
I’m not sure what that clue means, or if correcting it will solve the button layout, but it is a clue.
The first thing I would do is upgrade the core SLP plugin and any add-on packs you have to see if the error message and the layout problem are fixed.
Can you tell me which SLP Layout/theme you are using? (WP Dashboard> SLP> User Experience> View> Style> Select a Theme)
