When I first upgraded to 7.5.8 a few days ago, the A image was appearing after the Admin username and the M image after the Global Moderator username.
When, however, I did an Update Members on both the Admin and the Global Moderator, the image disappeared, however, the image still appears after my back-up Admin username, which I did not perform and Update Member thingy.
Is this a bug that you can tell me how to fix?
