MSCAN spamming CAN bus

Hello, I'm trying to send CAN messages from a MKE06Z128VLH4 running MQXLite using the MSCAN processor expert component.  I am able to receive, however, when I try to transmit, I send one message then the processor keeps spamming the same message repeatedly.

 

I am sure my code is not sending the messages repeatedly. So the MSCAN driver must be...

 

My code is as follows:

 

LDD_CAN_TFrame FrameTX1;

uint8_t frameData[] =

    { 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff };

LDD_TError error;

 

FrameTX1.MessageID = (message.id | 0x00000000);

FrameTX1.FrameType = LDD_CAN_DATA_FRAME;

 

FrameTX1.Length = 8;

FrameTX1.Data = frameData;

error = CAN_SendFrame(g_CANPtr, 1U, &FrameTX1);

if (error)

{

    _mutex_lock(&g_printMutex);

    printf("CAN TX 1 ERROR : %d\n\r", error);

    _mutex_unlock(&g_printMutex);

}

 

I do not receive any errors. I can see the messages being spammed repeatedly on my scope. Is there something in the component I set up wrong?
