Can you try the following:
pageextension 50100 PageExtension50100 extends "Business Manager Role Center"
{
layout
{
modify(Control139)
{
Visible = false;
}
}
actions
{
}
}
It might be another rolecenter page that you are using. You can find out by going into your sandbox, then click the design option (under the menu radar), then remove the headlines, then stop design and save the file)
