Inside your map.js file can you try updating the sharrre initialization code to what's below?
$('#shareme').sharrre({
share: {
googlePlus: true,
facebook: true,
twitter: true,
},
buttons: {
googlePlus: {size: 'tall', annotation:'bubble'},
facebook: {layout: 'box_count'},
twitter: {count: 'vertical'},
},
enableHover: false,
enableCounter: false,
enableTracking: true
});
(adding in "annotation:'bubble'" for googlePlus)
