Floating social doesn't behave as I expected

I have a couple of issues with floating social
1) 'Like' on the FB button translates in Dutch 'Vind ik leuk'. That is quite some text. Instead of the text I should use the thumbs up or down. Otherwise I need a widht of say 100. Is that possible?
2) Twitter button doesn't display, neither does pinterest. Is there a max of three buttons? Or do I have to check something extra?
