Can not reproduce it in QGIS 2.8.1 on Windows 8.1. Thought you might have a "hidden character" like a carriage return. This will show the category twice, but still for me with different colors. If you have a download link to some sample data addressing this issue, I would be happy to try it out on my machine.
