Bug to report : Copying a visualization from an existing visualization and then changing dimension not work.

[MeehyeOh]

I have a Qlik Sense Bug to report. 

Copying a visualization from an existing visualization and then changing dimension not work if the color of the chart is a class. Only if the color of the chart is a class.

After creating scatter chart using chart suggestions function, color it with 'Color by measure - Diverging classes'.

And then I copying scatter chart, tried to change dimension with other field from asset panel Fields through drag and drop into copying scatter chart.

However, in "Properties panel", the dimension appears to be a field changed to drag and drop, but there is no change on the screen.

So when I refresh my browser, the visualization appears as a white blank screen.

I've tested several things and this behavior only occurs when the color of the chart is 'Color by measure - Diverging classes or Sequential classes'.

Any help would be appreciated.
