Sharedaddy icon display problems

Hi, I’m having some problems with displaying some icons in posts using sharedaddy. In particular, the Twitter smart button and the Facebook like button both do not display correctly at the end of a post. In the case of the Facebook like button, there is a large gap between this and the following icon. In the case of the Twitter smart button, it is not horizontally aligned (moves a pixel or two downwards). There are no problems if using the facebook default/share buttons, or the standard small Twitter icon. It also makes no difference if ‘icon only’ or ‘icon + text’ are selected in the settings.
