Facebook vs. Pinterest conflict

I only have Tweet, G+, Pin & FB share activated on my site and it mostly works fine but sometimes the FB share button doesn’t appear at all and other times it is hidden behind the Pin button. Even if I deactivate the Pin button, the FB button still doesn’t show a lot of the time. Anyone know how to fix this?? Thanks.
