Simple On Off model not working along with Generic on off model [NRF MESH SDK5]

Question

Hi ,

I have added simple on off mode in my previous application which was based on Generic ON OFF model. Code for simple on off model is added in both server and client side and compiling without errors. When I provision my devices it only provision for Generic On Off model not the simple on off model and my clients can send data to servers without issue on generic on off model but same is not working on simple on off model

I have made following changes in server code for the addition of simple on off model

1- Increased ACCESS_MODEL_COUNT by one in nrf_mesh_config_app.h

2 - Changed ACCESS_ELEMENT_COUNT to 2 from 1 .

3- Called simple_on_off_server_init(&m_simple_server_0, 1)) just before app_onoff_init(&m_onoff_server_0, APP_ONOFF_ELEMENT_INDEX)); in model_init function.

and following changes in client code for the addition of simple on off model

1- Increased ACCESS_MODEL_COUNT by one in nrf_mesh_config_app.h

2 - Changed ACCESS_ELEMENT_COUNT to 2 from 1 .

3-

static void models_init_cb(void)
{
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Initializing and adding models\n");

     // these 2 lines are added
     m_simple_clients[0].status_cb = simple_status_cb;
     ERROR_CHECK(simple_on_off_client_init(&m_simple_clients[0],1));


    
    for (uint32_t i = 1; i < CLIENT_MODEL_INSTANCE_COUNT; ++i)
    {
        m_clients[i].settings.p_callbacks = &client_cbs;
        m_clients[i].settings.timeout = 0;
        m_clients[i].settings.force_segmented = APP_FORCE_SEGMENTATION;
        m_clients[i].settings.transmic_size = APP_MIC_SIZE;

        ERROR_CHECK(generic_onoff_client_init(&m_clients[i], i + 1));
    }
        
}

4- Called simple_on_off_client_set( &m_simple_clients[0], true) from button event handler.

The issue is only generic on off model is working but simple on off is not. Please guide about the issues of model not being setup during provisioning as the logs from the client shows only model id of health server and generic on off .

Following are the logs generated on client side.
