Using MATLAB offline converter on a specific 3D data results in incorrect scatter (2d) traces

Hello,

I am using MATLAB-Online project to convert several types of MATLAB figures.

When converting offline a specific data file, I got a problem. The data output contains correct scatter3d traces and some incorrect scatter (2d) traces.

The conversion seems to generate scatter (2d) when all the points are null.

Here is the demo data I was using:
S0307904X13006549_mmc3.fig.zip

Here is an extract of the data output:

{"xaxis": "x1", "yaxis": "y1", "type": "scatter3d", "visible": true, "x": [null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null,
