Problem with getting IRQ from FIFO (MegaWizard)

Hello, i made a FIFO from the MegaWizard and imported some pins inside SOPC Builder.

Basically i have rdreq and Q signals inside of my SOPC Builder and all others signals outside.

I have instanciated my SOPC systme like this

                     //fifo
                     .clock_to_the_novoFifo_0          (CLOCK_50),
                     .data_to_the_novoFifo_0           (data_in),
        //             .empty_from_the_novoFifo_0        (empty_from_the_my_fifo),
                     .full_from_the_novoFifo_0         (wrfull),
                     .almost_full_from_the_novoFifo_0 (wralmostfull),             
                     .in_port_to_the_pio_0            (pio),
                     .wrreq_to_the_novoFifo_0         (wrwrreq)
                );

I am trying to get the almost_full and full_signals but they are always 1, why?

I am writting in my fifo like this:

        if(full==0)
            begin
                wrreq <= 1;
                FIFO_DATA <= FIFO_DATA+1;
                    if(almostfull)
                        pio<=1;
            end
        if(full==1)
            begin
                wrreq <= 0;
            end

but almostfull and full signals are always 1, really weird.

Both my SOPC Fifo and my Always block that writes inside it have the same clock (50 mhz).
