I sent a query that includes 2 questions to unbound and received a "format error" response,dose unbount support this?Or I should add a special configuration?

I'm sure that the query I sent has right format,you can see the format as below(mtlxy.com is a local zone and has the www and ftp records):

Domain Name System (query)
    [Response In: 2]
    Transaction ID: 0x0000
    Flags: 0x0100 (Standard query)
        0... .... .... .... = Response: Message is a query
        .000 0... .... .... = Opcode: Standard query (0)
        .... ..0. .... .... = Truncated: Message is not truncated
        .... ...1 .... .... = Recursion desired: Do query recursively
        .... .... .0.. .... = Z: reserved (0)
        .... .... ...0 .... = Non-authenticated data OK: Non-authenticated data is unacceptable
    Questions: 2
    Answer RRs: 0
    Authority RRs: 0
    Additional RRs: 0
    Queries
        www.mtlxy.com: type A, class IN
            Name: www.mtlxy.com
            Type: A (Host address)
            Class: IN (0x0001)
        ftp.mtlxy.com: type A, class IN
            Name: ftp.mtlxy.com
            Type: A (Host address)
            Class: IN (0x0001)
