SClogin appears outsied menu dropdown container

in the drop down of my main menu the sclogin appears outside of the dropdown container
wightshops.com/ - 'sign in' tab
Does not appear to be a problem with the menu as the SCwidget displays correctly, Same menu > 'community' tab (dropdown shows invite a friend within the dropdown container)

To test I have set the template on another site to the same as the one with the problem - www.lovecampsites.com/en
Here all displays correctly > Main Menu > Community

Any help to get this looking correctly would be much appreciated
