Why is Universal reference being treated as R-Value reference?

I thought T&& in void func1(T&& t) should be deduced as a universal reference or a forwarding reference [...]

No. t in your example is not a universal reference. To be a universal reference it must be deduced from the call, but in your example T is just A. This is a universal reference:

template <class T>
class Test
{
public:
    template <typename X>
    void func1(X&& t)
    {

    }
};

The important detail is "deduced". In your example nothing is being deduced. Consider that Test<A> is equivalent to

class TestA
{
public:     
    void func1(A&& t)
    {

    }
};

Once you instantiated the class template, its method func1 has argument of tpye A&&, not something else, ie there is nothing to be deduced anymore. Template argument deduction takes place when you do not explicitly state the template argument, as in

 template <typename T> void foo(T&& t) {};
 
 foo(1);
