I don't understand what you are doing. You say "if the number is >0", but you are comparing if one array of numbers is greater than an array of numbers {1,2,3,4,5,6}. If when you convert those comparisons to a boolean array to a number, you see if that is greater than 0. That is effectively the same as OR array elements. If any of the values are greater than the corresponding element in your 1...6 array, then you are true. You stop the loop and do it all over again.
I'm not clear on what you are reinitializing. If you want to reinitialize the queue point by point, then you should wire the boolean into that connector of the subVI.
I think you have one or two too many levels to this VI, What is supposed to happen in the False case? Other than the very first time this VI runs, and in that event, you wire a true into the shift register and immediately go into the true case. It will never run the empty false case again.
You should be able to do this with a single while loop!
