Please show us where excel and file IO happens. I cannot find it.
Your VI is full of race conditions and very convoluted code.
To get one row of a 2D array, reshaping it to a 1D array with the lenght of one row seems pointless. All you need is "index array" with one index disconnected.
You have a case structure with the same property nodes in all case frames, thus they belong after the case, only on instance needed each.
There are plenty of potential race conditions. For example the boolean "standard" is read (via value property) and written in parallel elsewhere to the terminal.
How do you know what happens first?
Getting a scalar from an array does not need a detour via dynamic data ("Numeric", after the small FOR loop). try 
index array"
In the "next: mouse down" event, all you need in the second frame is the "menu" local variable. wire it to the output if the +1 from the previous frame.
