No, I changed it to a pictures of myself. The soulglo one is my old avatar. If you go to my page, it shows my pic avatar. As far as it taking a while to cache, I did this several weeks ago.
I checked your profile and the avatar is correct. The profile picture is also correct. The problem is that those two are not the same i.e. you have the SoulGlo as the avatar and yourself as the picture.

I would suggest you try to upload it again. If you are still having problems, send me a PM or open a ticket using the Contact Us link (top right).
