If you attached a VI rather than a picture, we might be able to help figure that out.
Why are you using a local variable of the array in the inner most case structure rather than the array wire that is right there? It is possible you have a race condition where the value in the Array variable is read before the latest data is written to the Array terminal.
Are you sure you have more than 3 rows going to the Write to Spreadsheet File? Have you tried running with probes? Put extra indicators in there to see what the dimensions of the 2-D array actually are?
