Initial High Frequency Waveform When Using the NI ELVIS Function Generator Express VI

Primary Software: Driver Software>>NI ELVIS Driver VIs
Primary Software Version: 2.1
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: Multifunction DAQ (MIO)>>Connector Blocks>>NI ELVIS

Problem:
The Function Generator Express VI initially produces a waveform at a much higher frequency than I specified. Is there some way to avoid this?

Solution:
Each time the Function Generator Express VI starts, the Function Generator is initialized which produces this high frequency signal.
If you want to change the waveform without seeing the high frequency waveform, run the Function Generator in a While Loop with the stop condition of the loop wired to the stop terminal of the Function Generator Express VI, as shown below.
