VI Fails to send queue elements

I am trying to use a queue to send data from my pulse train subVI to my main VI.

After my pulse train completes, I send a TRUE boolean via the 'Enqueue element' which goes to the 'Obtain Queue' and then to the Dequeue Element to acquire and log data.

I am not sure why the data is only sent the first time, and not consequentially.

I've tried the same with the Notifier to no awail. I am not sure if this is an issue in my SubVI or my main VI.

I am not sure if this is correct? Do I need to release the reference or something?

Thanks!
