Target dropdown displays the "User" option twice

When creating a documentation page, the "Target" dropdown shows the "User" option twice. The first "User" comes from the default value, which causes the target field to be empty. This can be seen in the documentation violation message, where the "target" is missing (e.g., “Please edit [DocApp.Data.NavigationDevGuideFors] to add it...”), since [DocApp.Data.NavigationDevGuideFors] cannot find the target.
