You still have the race condition that Mark pointed out. Putting the latches in a sequence helps some, but doesn't keep the case statement from executing before or after the sequence.

I think you can implement the whole thing using wires and feedback nodes, and then you would have no race conditions.

As for any specific debugging, that's almost impossible to do with a PDF of a portion of the code, and hardly any description of what the code is supposed to do. Post the VI and a detailed description and maybe someone can help. To me, it looks overly complicated, but since I don't know what its supposed to do, I can't say for sure.
