buttons in enfold theme not displaying correctly

hi

i am having an issue with buttons on the home page of my site. below is the code i am adding which should display 2 big blue buttons with text and icon.

>>>>
[av_button_big label='Send An Enquiry >>' description_pos='below' link='manually,http://' link_target='' icon_select='yes-left-icon' icon='ue805' font='entypo-fontello' custom_font='#ffffff' color='theme-color' custom_bg='#444444' color_hover='aqua' custom_bg_hover='#444444'][/av_button_big]

[av_button_big label='Get a Quote >>' description_pos='below' link='manually,http://' link_target='' icon_select='yes-left-icon' icon='ue82b' font='entypo-fontello' custom_font='#ffffff' color='theme-color' custom_bg='#444444' color_hover='aqua' custom_bg_hover='#444444'][/av_button_big]
>>>

when first added the buttons displayed as they should – but after about 3 updates to other parts of the home page – the buttons have stopped displaying correctly. the button code hadn’t been changed and i have checked on both firefox and chrome and am getting the same problem.

you can see a screenshot of the page showing the problem by following this link – http://awesomescreenshot.com/0ff5f3ao0a – i have drawn a red circle round that part of the page where the problem is. i am running the latest version of wordpress and the latest version of the enfold theme – both updated earlier today.

any help much appreciated

thanks
