XF 1.5 Username CSS Visibility On Nodes


Hello there,
I was wondering if anyone is able to help me with this issue?

Issue: http://prntscr.com/dh4kxj
Example: http://prntscr.com/dh4mpc

In the (issue) screenshot, the arrow is pointing to one of the Administrators username where it would be red everywhere else, but on the node forum it isn't.
I was just wondering how to make it appear that groups username css like presented in the example screenshot.

- Thank you!
