Fixing a discontinuity in waveform graph data

[HGus]

Hello, 

I am graphing two signals into a waveform graph GUI using probe data in LABVIEW 2016. The issue I am having is the waveform is not continuous when the data is graphed and I do not know why.

So far I have tried VI's that remove a DC shift and another VI that shifts a waveform and none have worked. 

Here is the original VI:

* The AC Sig and Ref are put into a build array and the data is displayed on the Waveform chart in the "WVFRM GUI"

Attached is the two VI's involved with this system and the excel contains the graph with the continuity after graphing the data.

If you have any suggestions to solve this issue that would be much appreciated.
