360 degree phase error

I have two sets of similar simulation data but there is a 360 degree shift between the phases of the two.  It doesn't appear to me to be a phase unwrapping problem, and the data is almost completely identical.  This isn't a rare occurence and I can't figure out why it happens, or why it sometimes doesn't.  A simplified vi with the data stored as defaults in the controls is included.  I took away all other subvi's to make it as clear as possible.  I need to get this under control because I need to move away from the simulation and implement it in the real world.

Just standardize the phase to be in the range [0..360], easiest by using Quotient&Remainder. See picture.
