Documented symbol `enum ABC NamespaceA::NamespaceB::XYZ' was not declared or defined

In doxygen, I am getting the following warning: Documented symbol `enum DDD
NamespaceA::NamespaceB::XYZ' was not declared or defined.

The enum in question is not even documented in doxygen so I don't know why
the message above is showing up. Note that the enum is outside a class.

namespace NamespaceA {
namespace NamespaceB{
enum DDD XYZ {
    SORT_ASC      = 1,
    SORT_DESC     = -1
};
}
}

I have tried documenting the above enum, adding a \file tag to the file as
well. However, I still get the same warning message.

How do I get rid of the warning message ? I'm using Doxygen 1.8.10
