I've tried deleting the attributes on all my titles by editing and resubmitting as blanked. My first attempt I included an explanation, as I've never exhibited my work under Marez but it was not changed. All titles were entered via Withoutabox by people (usually family - not understanding importance of entering screen name) assisting with the projects over the years.
When I discovered the birth name vs screen name error, I figured I could just change it later when I had time (time flies). Well, I very much need to take control of my working name now. It has become a real world problem, causing confusion and missed opportunities in my working life. I've tried a second time to no avail as well.
