Error About ADP3450 with MATLAB_Digilent Toolbox

[dg22310]

Hello, i want to ask about How to ploting input signal on Matlab by using Addon(Digilent tool box) "Digilent Analog Discovery Pro 3450"
i just followed This link

https://digilent.com/reference/test-and-measurement/guides/matlab-getting-started

And I have problem like this
This is answer when i ask to Matlab forums. But he say ask to digilent....
https://kr.mathworks.com/matlabcentral/answers/2118976-how-to-ploting-input-signal-by-digilent-analog-discovery-pro-3450?s_tid=prof_contriblnk

The problem is....

This is code what i write on matlab

The input signals I provided two 1 MHz sine signals by AD2, Waveform softwere.
I plotted them in MATLAB by daq, digilent tool box addon , but I keep getting results from ADP3450 like this.

I don't know reason why i got this kind of result by using ADP3450...

And this is data what i got by using AD2, same way 

When using the AD2 (Analog Discovery 2), I encounter no issues. The MATLAB Digilent toolbox clearly states that the ADP3450 is supported, but why are the received signals appearing incorrectly?
