KB322853: The "Hide null/zero" option stops hiding nulls and zeros in a Visual Insight graph after adding new object to the graph in MicroStrategy Web 10.5

SYMPTOM:
When using Microstartegy Web 10.x, users can change the display of the Null or Zero values within a visualization by changing the setting shown below:

However, in Strategy Web 10.5, when the null or zero values are in a graph, if a user hides the nulls and zeros, using that function and then makes changes to the visualization, like adding a new attribute or metric, the nulls and zeros will appear again and the setting will no longer be able to hide them, as shown below. 
Before "Hide null/zero" is applied: 

After "Hide null/zero" is applied:

After adding an attribute or metric, nulls and zeros are back: 

STEPS TO REPRODUCE: 
Follow these steps to reproduce the issue in a Strategy Tutorial Project.

1. Create dashboard from data that contains nulls or zeros.
2. Display the dashboard as a Bar Chart.
3. On the Vertical dropzone add one metric, in the Horizontal dropzone add 2 attributes.
4. Click on the gear icon to access the Settings pane.
5. Select "Title and Container" from the dropdown and select Data Explorartion.
6. At the bottom, click on the blue "More Options" text.
7. Change "Show both Null and Zeros" to "Hide both Null and Zeros" and click save. Notice the setting works as expected.
8. Go back to the editor pane.
9. Add an attribute to the Color By drop zone. Notice the zeros and nulls appear again.

 
CAUSE:
This is an identified defect in Strategy Web 10.5. 
 
ACTION:
Currently this issue is still being reviewed for feasibility by our Technology team and it is not scoped for any upcoming scheduled Strategy release.
 
WORKAROUND:

1. Add the metric to the filter pane to create a metric filter.
2. Change the display style to qualification.
3. To hide all zero values, select from the dropdown, "Does not equal" and set it "0". This will hide all zero values. 
4. To hide all null values, select fromt the dropdown, "Is not null". This will hide all null values. 

There is no current way to hide both zeros and nulls through the metric filter option.
 
As an alternative, first design the visualization entirely and then enable the setting, to ensure no more manipulations will be done to the visualization after the setting has been enabled.
