SYMPTOM
in Visual Insight we have one report with attribute in rows and one in column with one metric.
the result has few null/zero values though we can hide them with the 'hide null/zero' check the problem comes when we want to display the total in columns, there all null/zero come back and can not be hidden.

STEPS TO REPRODUCE
1. Create a VI grid report with 1 metric with a at least one NULL value
2. Select hide data rows with zero/null values with a single click using the option: Data > Hide Nulls/Zeros, which is shown below.

3. The totals will still appear blank
CAUSE
This is working as designed in Strategy. The option to hide zeros/nulls only applies to metric values and does not extend to subtotals.
