Raid Social - # of each class in raid missing

[Shammytime]

I use ElvUi as well as Carbonite. Carbonite handles my social tab which includes the raid window. However, I am unable to figure out how to get the tab on right side of raid window to show how many of each class is in the raid. Am I missing something? I apologize if this was covered in forums somewhere, but I did my best to try to find before posting. Thanks!
