Those headers are now made up of 2 string resources:
1 - common.browse
2 - The string resource specified as the 'Header' attribute where that control is added to the skin:
Code:
<aspdnsf:EntityControl ID="ctrlEntityManufacturer" runat="server" Header="<%$ Tokens:StringResource, AppConfig.ManufacturerPromptPlural %>"
EntityType="Manufacturer" MaxMenuSize="<%$ Tokens:AppConfigUSInt, MaxMenuSize %>" />
If you don't want 'Browse' to display there, you can either change the common.browse string to say what you want instead, or set it to an empty string (don't just remove it).
