size of the received payload fixed ?

I am using RBPI3 with Ra_02
I am testing the rx_cont.py example, I have successfully get it to work with my board, however I am only receiving 5 characters payloads
I notice that rx_nb_bytes (which is equal to spi.xfer([REG.LORA.RX_NB_BYTES, 0])) is always returning the same value 9.
so the payload size is fixed to 9 bytes.
in the following example I tried to send the string "hello":
I got:
payload = [255, 255, 0, 0, 104, 101, 108, 108, 111]
first 4 elements are fixed no matter what message I sent.
the next 5 element are the byte representation of the characters that I have sent.
** THE PROBLEM **
why I can't receive more bytes ?

I can say this much: There is no 9 bytes limit to the payload.
