Do I have to dequeue each element separately?

Question

I have a series of arrays (hopefully in the attached vi is the right one) and a single dequeue for them all to a tdms write in my consumer loop. The problem im having is that im not getting all of the data into my tdms file. Only chunks of it. Why is that? Dequeue appears to only remove the last element, so does that mean I need like 50 dequeues and 50 tdms writes each with their own channel name in order to get all my data?

You need to have one dequeue for each enqueue to get all the data. You are enqueuing three times to the string array and five times to the numeric array in each iteration of the bottom loop.  In the top loop you dequeue three times from the string array and once from the numeric array.
Let's make a little example:
First iteration of lower loop:
String Queue:  1a, 2a, 3a
Numeric Queue: 1x, 2x, 3x, 4x, 5x
First iteration of upper loop:
Removed from String Queue:  1a, 2a, 3a.  Remaining in String Queue: -
Removed from Numeric Queue: 1x. Remaining in Numeric Queue: 2x, 3x, 4x, 5x
Second iteration of lower loop:
String Queue:  4a, 5a, 6a
Numeric Queue: 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x
Second iteration of upper loop:
Removed from String Queue:  4a, 5a, 6a.  Remaining in String Queue: -
Removed from Numeric Queue: 2x. Remaining in Numeric Queue: 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x
As you can see, the size of the Numeric Queue will continue to grow. 
WIthout spending much time looking at your code, my first thought is to an create array of the strings and enqueue that array. Similarly either concatenate the numeric arrays or make a 3D array and enqueue that. One enqueue for each type of data. One dequeue for each type of data. You might need to do some parsing before writing to the file.
