Length of RLRQ is not correct if using HLS with Security Suite 0

Hi there,
we´ve problems using HLS with Security Suite 0 (Library Version 2.2.17).
We are able to initialize the connection, it is even possible to do some get requests, but whenever we close the connection we get a "Length of RLRQ is not correct". There are no problems when using HLS Security Suite 1 or 2.

We use HLS with Authentication (HIGH_GMAC) and Encryption against the Meter Simulator of DNV GL.
Does anyone have an idea why this error occurs?

We use the following code:

GXDLMSSecureClient client = new GXDLMSSecureClient();

client.setInterfaceType(InterfaceType.WRAPPER);
client.setUseLogicalNameReferencing(true);
client.setAuthentication(Authentication.HIGH_GMAC);
client.setClientAddress(1);
client.setServerAddress(1);
client.setUserId(1);

client.setPassword(Util.hexStringToByteArray("30313233343536373839414243444546"));
client.getCiphering().setSecurity(Security.AUTHENTICATION_ENCRYPTION);
client.getCiphering().setAuthenticationKey(Util.hexStringToByteArray("00112233445566778899AABBCCDDEEFF"));
client.getCiphering().setBlockCipherKey(Util.hexStringToByteArray("00112233445566778899AABBCCDDEEFF"));

// If we use Authentication and Encryption with HIGH_GMAC and Security Suite 0 we get an error closing the connection
// (Length of RLRQ is not correct) for Meter Simulator
client.getCiphering().setSecuritySuite(SecuritySuite.AES_GCM_128);
// client.getCiphering().setSecuritySuite(SecuritySuite.ECDH_ECDSA_AES_GCM_128_SHA_256);
// client.getCiphering().setSecuritySuite(SecuritySuite.ECDHE_CDSA_AES_GCM_256_SHA_384);

IGXMedia media = new GXNet(NetworkType.UDP, "192.168.0.20", 4059);

When we initialize and close the connection with the code of your sample client we get the following payloads (already decoded with your Translator):
