Document and Media Portlet Zoom Button Issue

[Matt VanPelt，修改在11 年前。]

I am having a very strange issue. When accessing a document preview through the Document and media portlet, the zoom and left/right arrow buttons are not showing up correctly(see attached file). If I go into Documents and Media in the control panel, they show up normally. I am using Liferay 6.1 CE GA2 w/ tomcat and have imagemagick installed. Any help would be greatly appreciated.
