I can‘t understand the better GaloisKey creating with Microsoft SEAL?

Question

This is the description of GaloisKey in seal / keygenerator.h from the Microsoft SEAL-3.4 library :

/**
    Generates and returns Galois keys. This function creates specific Galois
    keys that can be used to apply specific Galois automorphisms on encrypted
    data. The user needs to give as input a vector of Galois elements
    corresponding to the keys that are to be created.

    The Galois elements are odd integers in the interval [1, M-1], where
    M = 2*N, and N = poly_modulus_degree. Used with batching, a Galois element
    3^i % M corresponds to a cyclic row rotation i steps to the left, and
    a Galois element 3^(N/2-i) % M corresponds to a cyclic row rotation i
    steps to the right. The Galois element M-1 corresponds to a column rotation
    (row swap) in BFV, and complex conjugation in CKKS. In the polynomial view
    (not batching), a Galois automorphism by a Galois element p changes
    Enc(plain(x)) to Enc(plain(x^p)).

    @param[in] galois_elts The Galois elements for which to generate keys
    @throws std::logic_error if the encryption parameters do not support
    batching and scheme is scheme_type::BFV
    @throws std::logic_error if the encryption parameters do not support
    keyswitching
    @throws std::invalid_argument if the Galois elements are not valid
    */
    SEAL_NODISCARD inline GaloisKeys galois_keys(
        const std::vector<std::uint64_t> &galois_elts)
    {
        return galois_keys(galois_elts, false);
    }

How can I create a better Galois elements for the GaloisKey.

In a general way:

GaloisKey gal_keys = keygen.galois_keys();

But Ciphertext first rotation is right，second rotation is wrong.

The specific error is, for example, one of my ciphertexts is [0.0001,0.0001, ... 0.0001], after rotation, the decryption is [1.0000,1.2000,1.7000 ...]
